About this gig

Do you need a custom HTML5 browser game or help fixing an existing JavaScript game?


I will develop, improve, or debug a responsive 2D web game that runs directly in modern desktop and mobile browsers.


I can help with:


  • HTML5, JavaScript and CSS game development
  • New gameplay mechanics and levels
  • Menus, scoring, sound and animation
  • Keyboard, mouse and mobile touch controls
  • Local saves and settings
  • Bug fixing and performance optimization
  • Analytics or advertising integration
  • Responsive adaptation for different screens
  • Preparing game files for web platforms
  • Clean and organized source code


Please provide your game concept, preferred style, required mechanics, target devices, and any graphics or audio you already have. Custom artwork is included only in packages that specify design.


The final scope depends on the selected package. Please contact me before ordering if your game requires multiplayer, complex backend features, advanced AI, or many levels.

Hi! I develop Telegram bots, Telegram Mini Apps, and HTML5 browser games using Python, JavaScript, HTML, and CSS. I build monitoring and notification systems, RSS and website tracking, keyword filters, user settings, API integrations, databases, and button-based interfaces. I also create FastAPI and SQLite backends. My experience includes media-monitoring bots, travel alert tools, and a browser game with trading, quests, combat, workshops, caravans, localization, and save systems. I can build new projects, add features, fix bugs, and improve existing code.
