Hello, I am very interested in your job posting titled Нужна платформа для проведение турниров CSGO. I possess the necessary PHP, JavaScript, CSS, HTML, jQuery / Prototype skills, and more. I have over 10 years of professional development experience. As a full-stack developer, I am an expert in both front-end and back-end development. I am experienced in HTML/CSS, JS+jQuery, PHP, Node.js, and CS:GO. I can develop functionality for MIX tournaments of 1x1, 2x2, and 5x5 with team tournament functionality. Only the team captain can invite players, and all teams will be listed for the admin to distribute. Let's collaborate for a long time! Thank you for taking the time and evaluating my proposal. I am eagerly looking forward to the opportunity to speak with you soon.
