Maciej — Full-Stack Web3 Engineer

Warsaw, PL · building web3 end to end · open to part-time remote contracts

Ten years on the web. Spent years as an Typescript/React/ReactNative + iOS/Swift developer, now work full-stack on web3 — the dApp frontends people touch and the backends behind them. I move fast, communicate clearly, and ship things that hold up in production.

What I work with

• Frontend — React, Next.js, TanStack Start, Angular, TypeScript
• Backend — Docker, PostgreSQL, Drizzle, Kysely, Node.js/Bun/Deno, Python
• Web3 — wagmi, viem, Ethereum, Solidity, on-ramp integration
• Mobile — React Native, Swift, Kotlin
• Also — Three.js, Rust, Bevy (gamedev, for fun)
