I've built and maintained web, mobile, and decentralized applications for Gempad, Piatto, Wege, and Onesaz. At Gempad, I developed token creation, presale, lock, and staking smart contracts across EVM, Solana, Tron, and TON networks.

I build end-to-end systems, from wallet connections, REST APIs, GraphQL, and Solana indexers to React Native applications with real-time messaging, push notifications, and accessibility-focused LLM features.

I've also delivered Java Spring Boot microservices, Android apps, and an OpenCV-based OMR system, with a focus on secure APIs, database performance, caching, reliability, and scalable production architecture.
