Companies and roles where I've built backend systems, automation, and the smart contracts behind them.
Freelance backend & automation for dozens of clients — low-latency trading bots, copy-trade/sniping strategies, and the Solana node infrastructure behind them, all run on Linux.
Built NestJS backends and the smart contracts behind a multi-network gaming wallet (9,000+ users), an NFT marketplace, and a fiat-crypto exchange.
Built the NestJS backend and Solidity contracts for a community-engagement platform — points, reward orchestration, and on-chain prize distribution.
