    Hi! I am looking to upgrade my current sales dashboard. I am looking for a Data Specialist who I can learn from and who can propose the best solution for my needs. Data will come from CSV files. I need a place where I can import that data to. I would like the dashboard to be as detailed as possible showing multiple KPIs, graphs, and correlations between the various data. Once setup, I would like it to be fairly simple to import new data, and modify the dashboard as needed over time. I would like this setup to be fully offline and local. My current thoughts are Metabase + SQLite. However I am open to other solutions and recommendations. I will be able to provide an example of the CSV during discussion to see how and what we can achieve with the data. I am looking for an individual who...

    I have an existing UNX universe already in daily use by the Sales team and I need an experienced SAP IDT developer who is equally comfortable with SAP S/4 HANA reporting to extend it and refresh our Web Intelligence sales dashboards. Scope of work • Universe updates: the job is strictly about modifying the current universe, not creating a new one. You will add the objects the analysts keep asking for—new dimensions, measures and hierarchies—so they can slice revenue, margin and forecast data the way they need. • S/4 HANA alignment: everything you add must pull from the correct CDS views or calculation views in S/4, with naming and aggregation rules that match the existing data model. • Report enhancement: once the universe is updated, I want at least three...

    I’d like a data-savvy partner who can dive into our raw inventory history and surface clear, actionable trends. The sole objective is to analyze historical data—specifically inventory data—so our team can understand how stock levels have moved over time and where the pressure points sit. Here’s what I have: several years of SKU-level records housed in a SQL database, plus a few CSV extracts. I need you to pull and clean the data, run robust trend analysis in Python (Pandas, NumPy, preferably some Matplotlib or Seaborn visuals), and package the insights so they are easy for our planners to act on. Time-series forecasting or demand planning frameworks aren’t required right now, but please structure the code so we could layer those in later if needed. Deliverab...

    I have a Hadoop cluster holding several large data sets, and I need a seasoned PySpark developer who also writes rock-solid SQL. The immediate aim is to connect to the cluster (YARN/HDFS with Hive metastore), develop or refine PySpark jobs, optimise the accompanying SQL, and make sure everything runs smoothly end-to-end. You’ll receive access to a staging namespace plus a sample of the data. Once the logic checks out we’ll promote the code to the full environment. Deliverables • A clean, well-commented PySpark notebook or .py job that executes successfully on the cluster • The corresponding SQL script or view definitions ready for Hive or spark-sql • A concise README detailing execution steps, parameters, and expected outputs Acceptance criteria &bul...

    I have a fully-functional ERP written in core PHP with a MySQL backend. The next milestone is an Inventory Management module dedicated exclusively to stock tracking. No supplier or order features are needed at this stage. What I need built • Database changes to record products, stock movements (in, out, adjustments) and current on-hand quantities. • Clean, responsive PHP screens that blend with the existing UI for item setup, stock transactions and a real-time stock level dashboard. • Basic search, filter and export to CSV so staff can pull quick counts. • Low-stock thresholds with email alerts (SMTP already configured in the system). • Clear install/merge instructions and brief user documentation. Acceptance The module must install without breaking e...

    I currently manage a website built for display management. It runs on a Linux server with an SQL database. Over time, the system has slowed down and is struggling to handle the increasing volume of data efficiently. The goal is to redesign the website using modern technologies and update the overall architecture to improve performance and scalability. All page designs have already been completed in Figma. The platform synchronizes its main database with local databases on connected desktop workstations, and the new version must remain fully compatible with the existing desktop software to ensure seamless synchronization. There are three user roles: Super Admin, Admin, and User, each with specific permissions to manage or view different levels of content. In addition, the UI needs to be...

    This project will create an end-to-end, AI-powered email delivery system for a U.S. client. All work must be carried out on-site or remotely from New York State; residency is a strict requirement because of data-handling policies. Scope of work The core task is to design, train, and deploy a regression-based machine-learning model that predicts optimal email-send parameters from rich transactional data. I will supply secure access to the historical transaction logs; you will architect the data pipeline, engineer the relevant features, and iterate on model performance until it is production-ready. Once validated, the model should be wrapped in an API and integrated into our existing email infrastructure so it can trigger personalized sends automatically. Key responsibilities • Da...

    I need a web-based application that lets me run every aspect of a high-school wrestling tournament from one screen. The core must cover participant registration, automated bracketing and seeding, match scheduling, real-time score tracking, live team scoring, and on-demand printing of brackets, bout sheets, and final results. Here’s how I picture the flow: • Coaches register athletes online, selecting weight classes and entering roster data. • The system seeds each bracket automatically yet allows manual tweaks when necessary. • Matches are scheduled across multiple mats and rounds, with clear matside displays. • Scores are entered live; individual results immediately roll into cumulative team standings. • At any point, I can print clean, ready-to-po...

    I’m setting up a central repository where each of my subscribed clients—schools, companies, public bodies and similar organisations—can log in over the internet to view, upload and download their own estate-related and compliance documents such as surveys, inspection reports and certificates. Editing in the browser isn’t required; the goal is a “read, upload, download” portal that keeps every file in its original form. Here’s what I need built: • A relational database (SQL or comparable) that stores the file-metadata and user accounts. • A clean web interface that works on desktop and mobile, served from my own on-prem server. • Username-and-password authentication with session timeout and password-reset functions. • Rol...

    I need a seasoned Tally user to build a complete book of accounts focused on inventory management and to configure the system so I can pull accurate financial reports any time I need them.
