I help clients build games and applications that actually run in production stable, scalable, and ready for real users. With over 13 years of experience and more than $600K earned on Upwork, I’ve worked on a wide range of projects including multiplayer games, mobile applications, simulation systems, and backend-connected platforms. Many of the systems I’ve built are used in real environments where performance, reliability, and long-term maintainability matter. A large part of my work involves stepping into existing projects that are already in progress. These projects are often unstable, difficult to scale, or poorly structured. I go through the codebase, understand how everything is connected, fix underlying issues, and restructure systems so future development becomes easier instead of more complicated. I’m comfortable working across the full stack. On the front end, I handle gameplay systems, UI, animations, and interaction logic. On the backend, I work with APIs, databases, authentication systems, and real-time communication. I regularly build and maintain systems that rely on WebSockets, live data synchronization, and event-driven architecture. I’ve built multiplayer systems for both real-time and turn-based games, including matchmaking, session management, and server-authoritative logic. I’ve also worked on simulation and strategy games where progression systems, resource management, and AI-driven behaviors are important. Idle systems, mission structures, and long-term progression loops are areas I’ve spent a lot of time optimizing. In addition to traditional games, I’ve worked on web-based experiences using Phaser.js and PixiJS, including promotional games, kiosk applications, and interactive installations. These projects often require smooth performance, quick load times, and a polished user experience across different devices. I also have experience in VR and AR development using Oculus SDK, OpenXR, and HTC Vive. This includes interactive simulations, training environments, and real-time 3D systems that require both performance optimization and strong interaction design. On the mobile side, I build applications using React Native (Expo), including authentication systems, real-time features, and backend integrations. I’ve worked with Supabase and Firebase for authentication, storage, and realtime systems, along with PostgreSQL and MySQL for structured data handling. I also integrate services like RevenueCat, push notifications, analytics systems, and app store deployment pipelines. I’ve worked with Unity (C#), Cocos Creator, Godot, and other frameworks depending on the project requirements. I’m comfortable choosing the right tool based on performance, scalability, and long-term maintenance rather than forcing a single approach. Most clients bring me in when something is not working properly or when their project starts slowing down due to technical issues. I focus on identifying root problems instead of applying temporary fixes, and I structure systems in a way that supports future growth. I keep communication clear and straightforward, and I work well with both technical and non-technical teams. Whether it’s building from scratch or improving an existing system, I focus on making sure the project is stable, maintainable, and ready for real users. If your project is already built but starting to feel messy, unstable, or difficult to scale, I can help bring it back under control and move it forward properly.
