What I'm looking for

I'm eager to bring my frontend, mobile, Web3, and backend experience to a fast-paced, collaborative, founder-led environment.

At ChainPlay, I founded and built a PvP competitive arcade on Solana, taking it from concept to working product. I implemented on-chain match creation, joining, settlement, and cancellation with Anchor and Rust.

I also shipped six skill-based PvP games with a dual-token economy and a 1.5% protocol fee model.

At Machi Kunzult Ltd, I built Machi Care, a telemedicine mobile application, using React Native. I developed its navigation, patient and provider flows, and API integrations, and built a management system with the MERN stack.

I also developed Machi HR, a companion mobile application, and worked on frontend development at Unikrib, including Google Maps integration. I founded and built BuyMeSuya, a creator tipping platform with a Next.js frontend and a Node.js, Express, and PostgreSQL backend.
