Project: Full-Stack Developer for Anime Streaming Website (React + Go) Project Overview We are developing an anime streaming website and already have a functional front-end completed. The current goal is to improve the quality, responsiveness, and overall user experience of the front-end, while also building and refining a scalable back-end system. This is a two-month project, and payment is open for discussion based on experience and project scope. Front-End Requirements The front-end is built using ReactJS, JavaScript, HTML, and CSS. The work involves improving UI and UX quality, making the website fully responsive across all devices, optimizing performance, and refactoring existing code where necessary to enhance maintainability and visual polish. Back-End Requirements All anim...

I need an experienced Angular developer to jump on AnyDesk with me and get a fresh project up and running on my machine. This is a single-session engagement: once the app builds, serves, and I can rerun it on my own, we’re done. During the session you’ll initialise the workspace, install and configure the necessary dependencies, lay out a clean folder structure that follows current best practices, and verify everything compiles without errors. If there’s a smarter way to organise modules, services, or shared assets, I’m happy to follow your lead. You must be comfortable driving the setup while explaining what you’re doing so I can maintain the project afterwards. Clear spoken English, a stable connection, and availability to start immediately are essential. ...

I’d like a high-fidelity interface demo built in Figma ( is fine if you prefer) for a forthcoming web application. The primary objective is to showcase polished visual aesthetics that mirror the brand guidelines I’ll share with you at kickoff—logo files, color palette, and typography are all ready to drop in. You’ll receive a concise feature outline and a few user-flow sketches; from there, translate them into clean, responsive screens that feel modern yet consistent with the brand. I’m after realistic styling rather than wireframes, so please lean on components, auto-layout, and smart prototyping to bring the pages to life. Deliverables • High-fidelity mock-ups for each core screen (desktop first, tablet/mobile variants appreciated) • An inter...

I need a single, conversion-focused web page for my new e-commerce venture, built entirely with clean, well-commented HTML5 and CSS3. The page will act as our business’s online front door, so polish and responsiveness across desktop, tablet, and mobile are non-negotiable. Core layout • Services Offered – a concise, visually engaging overview of what we sell. • Client Testimonials – sliding or card-style quotes to build trust. • Contact Form – name, email, and message fields with front-end validation; back-end hookup can remain a placeholder for now. Style & code expectations • Modern, minimalist aesthetic that keeps the focus on our products. • Semantic markup, BEM or similarly clear class naming. • External CSS only; ...

I run a React + Node.js web application backed by PostgreSQL and Prisma, and I’m looking for a junior full-stack developer who is comfortable working in Arabic to help me ship a series of small but important enhancements. (Put your price for: Duration: 15 Hours in one week) The immediate priorities are: • Building an interactive dashboard that consumes our existing REST endpoints and presents data in a clean, responsive layout. • Refining the overall user experience—tidying up flows, polishing micro-interactions, and ensuring consistent design language. • Extending both the frontend and backend as needed: new UI components in React, new routes/controllers in Node.js, and the corresponding Prisma queries for PostgreSQL. On the frontend you’ll mostly ...

I’m putting together a proof-of-concept and need a single-page web app, built in React, that mimics the look and feel of Dexscreener but runs entirely on simulated data. Candlestick charts must be rendered with , while the surrounding stats—price, 24 h change, market cap, volume, etc.—update in real time. Flow I envision • A Telegram bot (already under my control) sends JSON payloads with the latest price, market cap and any extra metrics I decide to test. • A lightweight server receives those webhook calls and streams the data to the front-end (WebSocket or SSE—whichever you find cleaner). • The React UI redraws the active candle and refreshes all displayed figures instantly, giving the impression of a live market feed. Key requirements &...

My 15-18 page site is functionally complete; it simply needs a sharper, more professional look. The main priority is typography—establishing a clear hierarchy, choosing a refined font pairing, and ensuring consistent spacing and rhythm across breakpoints. The existing color palette and layout work well enough, so keep structural changes minimal and focus on elevating visual polish rather than adding or removing features. I’ll give you Git access to the current codebase plus a staging URL. Work directly in the components, global styles, or utility classes as you see fit (CSS Modules, styled-JSX, Tailwind, or plain Sass—whatever fits smoothly into the project). No wireframes or references are provided; I trust your design judgment. Deliverables • Updated styles comm...

I’m building a business-management SaaS platform using Blazor with MudBlazor as the component foundation, and I’m looking for a UI/UX designer to shape the entire user experience before front-end implementation begins. The same design language must feel natural: • In a browser • Inside a desktop shell (e.g. .NET MAUI) • On mobile screens Responsive, multi-platform thinking is required from the first wireframe onward. This is not a Figma-only role. Every design must be implementable in MudBlazor using Blazor-friendly CSS and design tokens. What you’ll do • Translate existing user flows and rough sketches into: ○ High-fidelity mockups ○ Clickable prototypes • Design core system-defining screens, including: ○ A data-rich analytics das...

I need hands-on assistance, at my Bengaluru office, to keep a live .NET 6 back end and Angular 12 front end running smoothly. The immediate focus is two-fold: • Systematic bug fixing—tracing issues in the Web API, Angular components, and integration layers, then committing clean, tested patches. • Regular code reviews—walking through pull requests with me, flagging design or performance concerns, and suggesting improvements that align with current best practices. Expect to work directly on the existing Git branch structure (Visual Studio / VS Code, Git, and typical dev-ops tools are already in place). Face-to-face collaboration during standard weekday hours is essential; remote work is not an option for this engagement. Deliverables will be accepted once each id...

I need a clean, production-ready front-end for an ERP application built with React and Next.js. The back-end team will expose REST/GraphQL endpoints, so my main focus now is a modern, responsive interface that can consume those APIs and present data efficiently. What I expect from you: • A project scaffolded with the latest stable version of React, organised by feature modules so future sections of the ERP can be plugged in without refactoring. • Reusable components for common ERP screens (login, dashboard shell, data table with search/sort, modal forms, notifications). • State management wired up (Redux Toolkit, Zustand or another lightweight option you are comfortable with) and ready to connect to external endpoints. • Routing set up for at least a Home / Dashboard...

I have a fully built investor dashboard UI in HTML, TailwindCSS, and JavaScript. I need an experienced Firebase developer to connect the system to: • Firebase Authentication • Firestore Database • Investor login system • Admin panel (CRUD investors, holdings, deals) • Fund request system • Production deployment The UI is already complete. Task is backend integration only. Requirements: • Strong Firebase experience • JavaScript expert • Firestore schema design

I have a finished Figma design that I now need translated into clean, well-structured HTML built on the latest Bootstrap framework. The goal is a pixel-perfect match with the layouts already approved in Figma, relying solely on Bootstrap utilities and a lightweight custom stylesheet—no JavaScript is required for this phase. Key points I want you to keep in mind while coding: • Use semantic HTML5 elements and Bootstrap 5 classes so the markup stays readable and easy to maintain. • Keep any custom CSS in a separate file, clearly commented, and limit overrides to what Bootstrap can’t handle natively. • Ensure the pages fluidly adapt from desktop down to mobile widths; I’m expecting the usual responsive breakpoints covered by Bootstrap. • Optimize i...

I already have a fully-functioning web application and all the Play Store listing graphics (icons, feature graphics, screenshots, banners). What I need now is for someone to turn that site into an installable Android application and walk it all the way through publication on Google Play. The scope is straightforward: • Wrap or rebuild the existing web app into a compliant Android package (AAB preferred). • Configure signing, versioning, and any required permissions. • Create the store listing using the assets I will supply, fill out the content ratings and policy forms, and submit the release. • Hand back the final source, the signed AAB, and confirmation that the app has passed Google’s review or clear guidance on any requested fixes. If you have recent e...

I’m ready to take from a simple landing page to a fully-functional live baseball experience where visitors can watch the action and wager on the very next pitch. Core build • Real-time betting interface – odds and bet slips must update in milliseconds so users can lock in a wager before the pitcher winds up. • “Game Guru” admin console – a single operator should be able to appear on screen with Video commentary, speak over the stream in true live-TV style, and moderate chat or abusive behavior on the fly. Technical notes I’m flexible on stack, but latency is critical. WebSockets (Node.js, Phoenix, or similar), a modern front-end framework such as React/Vue, and secure payment APIs are the baseline I’m expecting. Integrate wha...

I have an app concept that I want to bring to life as a fully functioning web application. I already have the core idea in place, but I need an experienced developer to guide the technical direction, choose an appropriate stack, and build the first working version. Here’s what I expect from our collaboration: • Help me refine requirements and map out the feature set. • Recommend the best frameworks, libraries, and hosting approach based on long-term scalability. • Develop clean, well-documented code and set up version control from day one. • Keep me in the loop with frequent check-ins, so we can iterate quickly and avoid surprises. • Hand over a deployable, bug-free web app and any setup documentation I’ll need to maintain it. If you’re ...

I have a live React.js application that needs a refresh on both looks and behavior. I will hand over all existing code, REST APIs, and design references; what I need is a developer who can quickly plug in and push the project forward. First, the interface needs attention. Several screens require a new layout structure and an updated color palette that aligns with our latest brand guidelines. I’ll supply Figma frames so you can translate them into clean, responsive JSX and CSS (or styled-components if you prefer). Alongside the visual lift, some functional pieces must evolve. A couple of small-to-medium features are still on the backlog, and a few of our current components need polishing to make them more robust. All calls to the backend are already exposed—your task is to wir...

I need a fully-functioning application that streamlines day-to-day business management from a single, responsive dashboard. The core goal is to move tasks I currently juggle across spreadsheets, emails, and standalone tools into one cohesive web app built entirely in Bubble.

I’m building a small C# utility that will crawl a target site, pull out every piece of on-page information I need (both the visible text and the images), and also save any PDF that the page links to. The PDFs aren’t generated on the fly—each one is simply a normal hyperlink sitting in the HTML—so the job comes down to fetching the page, parsing for the data, spotting the *.pdf anchors, and downloading those files to disk. You are free to approach this with HtmlAgilityPack, AngleSharp, HttpClient, Selenium, or any other .NET-friendly library you’re comfortable with, as long as the final code is clean, asynchronous where it makes sense, and easy to extend. I will pass in the root URL (or a list of starting URLs) plus an output folder path; the tool should handl...

Je souhaite harmoniser toutes les notifications automatiques de ma boutique WooCommerce ainsi que celles générées par le plugin BookingPress. L’objectif est d’obtenir des emails HTML cohérents avec notre charte graphique interne, à la fois sur desktop et mobile. Voici les grandes lignes : • Créer (ou adapter) chaque modèle d’email par défaut de WooCommerce et BookingPress en version HTML. • Respecter la charte : palette de couleurs principale, typographies et logo de l’entreprise doivent être intégrés de façon élégante. Je privilégie un rendu visuellement coloré plutôt que minimaliste. • Veiller à la compatibilité : l...

I need a production-ready object detection model built, trained, and packaged so it runs smoothly on iOS and Android devices, in a modern web browser, and as a lightweight desktop application. The same model should power every platform to keep accuracy and behaviour consistent. You are free to choose the framework you are most comfortable with—TensorFlow, PyTorch, YOLOv8, Detectron2, or another proven library—as long as the final artefacts meet these requirements: • Mobile: optimised builds (e.g. TensorFlow Lite, Core ML, or ONNX) that hit realtime speeds on mid-range phones. • Web: WebAssembly/WebGL or implementation that loads in under three seconds on a standard connection. • Desktop: a small executable or Python app with GPU support when available and ...

We are looking for a creative UI/UX Designer to craft a high-impact, user-centric interface for a premium travel blog.

Key Objectives Visual Storytelling: Create a layout that prioritizes high-resolution imagery and video integration without sacrificing readability. User Engagement: Design intuitive "pathways" that lead readers from one destination guide to the next (reducing bounce rates). Mobile-First Approach: Ensure the experience is seamless for travelers accessing the site on-the-go. Deliverables Required User Flow Map: Mapping the journey from the homepage to specific ...

I’m launching a dedicated platform that will stream T20 matches in real time. Live video is the centrepiece, so the build has to handle an uninterrupted HD feed, adaptive bitrate (HLS or MPEG-DASH), and a responsive player that works on desktop and mobile alike. Beyond the core stream, I’d like the framework kept flexible: an area for quick score widgets, space for articles, and the option to turn on login-gated or premium access down the road. Think of it as a lightweight version of the big sports portals—purpose-built for T20 yet scalable for future series or even other formats. Key deliverables • Front-end interface (React, Vue, or plain HTML/CSS/JS—your call) with an embedded, responsive video player • Back-end service (Node, Laravel, or simi...

I have an existing React app and need the key pieces of the Polymarket privy-safe-builder example wired straight in. The focus is on two things: • User authentication & management – replicate the Privy-powered flow so users can sign up with email or social, link a wallet, and stay logged-in across sessions inside my project. • Smart-contract interaction – expose the same Safe-based contract calls shown in the repo (read, write, signature gathering, error handling), but adapted to the contracts my dApp already references. The codebase you’ll be grafting onto is a standard Vite + React setup with already in place. I’ll add you to the Git repository once we start; you can work in a feature branch and open a pull request when complete. Acceptance crite...

I want to launch a reels-centric news product that starts in English and Hindi and can later expand across India.

I have roughly 30 slot game files built entirely with plain HTML, CSS, and JavaScript—no external libraries or frameworks. When I launch them, certain functions refuse to fire and the console fills with both syntax and runtime errors. Here’s what I’ll provide: • Full source folders for each game • Step-by-step reproduction notes • Detailed browser console logs What I need in return: • Clean, well-commented fixes that eliminate the current syntax and runtime errors • Assurance that every game spins, pays out, and resets exactly as designed • Compatibility when hosted locally (e.g., from a simple HTTP server) and when deployed to a public website • A short report outlining what was broken, what you changed, and any best-pra...

Project Overview We are looking for a talented Graphic Designer to design a professional, modern, 4-page A4 brochure for BOMAX, a specialized Cloud-Based ERP for the Glass Industry. BOMAX is not just software; it’s a high-performance system designed for precision and data security. We do not want a "salesy" or "pushy" brochure.

I’m looking for someone based in Kollam, Kerala who can jump straight into an existing React web application and keep the momentum going. The core codebase is already live, but new screens, tweaks to component logic, and a round of performance fixes are pending. You’ll be working directly with me; I’ll walk you through the current repository, explain the backlog in Git, and hand over access to our staging server so you can ship updates quickly. Because the project is already in production, I need clean, modular code, familiarity with modern React hooks, and an eye for maintaining consistency with our current styling approach (we’re on CSS-in-JS). A solid grasp of RESTful APIs and version control in Git is a must, as those are central to the workflow here. Delivera...

I need a small web application that reads my existing Esri .GDB (fields include State, District, Sub-District, Village Name, PIN, etc.) and presents the data on an interactive map. From a single screen I must be able to: • choose a record either by selecting a PIN or a Village from a drop-down list or by typing into a Google-style search bar, • have the map zoom to that feature and instantly show its attributes, and • generate a printable report that looks and feels like the ones on —PIN is the key detail that must appear. Standard mapping tools such as measure distance/area, pan, and rotate are required. The interface must also let me upload additional layers (KML, JSON, SHP) and, after editing or selecting a feature, download the result in any of those three fo...

I have an existing scheduling code-base written entirely in JavaScript. At the moment its only fully working feature is the user-notification system, yet the app is already showing performance bottlenecks that slow page loads and make real-time updates feel sluggish. What I need first is a thorough cleanup and refactor that targets performance: untangle duplicated logic, remove dead code, split oversized functions, and trim the bundle so it ships fast. While you work, please leave the code more readable and well-documented so future contributors can follow along without guesswork. Your primary deliverable will be a redeployed build that runs noticeably faster on both desktop and mobile. If you spot bugs on the way, squash them—clean tests must pass before hand-over. After that,...

I need full source-code replicas of the slot titles released by Pragmatic Play. Every visual, audio, math model and game mechanic must match the originals exactly, including bonus rounds and free-spins sequences, while delivering the same high RTP percentages players expect from the provider. The build has to sit inside a back-office that lets me create, credit and deduct balances for whoever plays i want login screen, review detailed game logs and change RTP settings per title. An RNG that can be certified is essential, as is clean, well-documented code that my own dev team can later extend. Progressive jackpots are not required at this stage, but keep the architecture flexible so we can bolt that on later without a rewrite. Feel free to use any proven game framework or engine you are c...

I run a neighbourhood butcher shop and need a mobile-first site that feels modern and clean. Its main job is to tell visitors who we are, show them today’s cuts, then let them tap a single WhatsApp button to place an order—no payment gateway, no checkout flow. The launch version will include: • Home – our story, opening hours, map and a fixed “Order on WhatsApp” call-to-action • Products – a simple photo grid with name, price / kg and a deep link that opens WhatsApp pre-filled with the chosen product Performance and SEO matter: please build with semantic HTML5, lightweight CSS, optimized images, proper meta tags, Open Graph and basic Product schema so we rank in local searches. A fast, responsive experience from 360 px up to desktop is non-...

I’m building a responsive web app that shows where every train is right now, updating live on an interactive map. The core of the job is wiring reliable, real-time location data to a clean front-end that feels modern and snappy on desktop, mobile, and tablet alike. Here’s what I need from you: • A map-based interface that plots each train and refreshes automatically without manual reloads. • Search or filter so users can jump straight to a specific train or line. • Smooth zoom, pan, and click interactions consistent with a “modern and interactive” design ethos—subtle animations, hover states, and clear iconography rather than flat text lists. • Fully responsive layouts; breakpoints should feel native on phones, tablets, and large m...

I need an application that replicates the end-user experience of Google’s Gemini while letting me supply my own API key. Once the key is entered, every feature must unlock automatically—no hard-coded credentials. Core functionality • Full AI feature suite: chat-based text generation with streaming responses, image generation, and robust LaTeX rendering (MathJax or KaTeX are fine as long as formulas display crisply across devices). • Clean, responsive interface that mirrors Gemini’s conversational flow, shows conversation history, and supports markdown, code blocks, and inline math. • Simple “Settings” panel where I paste or update the key; all calls should route through that stored key. • Modular codebase so I can later swap models...
