At Quecko Inc, I design and maintain backend systems for gaming, fintech, SaaS, and Web3 applications. I work on REST APIs, GraphQL services, and real-time features such as matchmaking and multiplayer interactions.

As the sole backend engineer on Queen Wars, I architected and developed the backend for a real-time multiplayer chess platform, including matchmaking, tournaments, rankings, and live game-state synchronization.

Earlier, through Upwork, I delivered backend solutions for clients across SaaS, fintech, gaming, and blockchain. I also developed and maintained Android applications at Developerz Institute.
