Armenia

Message

At Thrive.io, I develop web applications for clients, design application systems, and maintain existing projects. On Rustiming WPC, I developed tournament scheduling and bracket generation, and built the foundation for live scoring with real-time updates.

I've also designed and implemented backend services for projects including a powerbank rental service, where I refactored a high-load geolocation service and reduced average response time from about 800 ms to 120 ms. My work spans Go, JavaScript/TypeScript, and Python, as well as commercial frontend development with React.
