01. ABOUT ME

Hello world. I'm a full-stack engineer building reliable systems on both sides of the stack — smart contracts and on-chain protocols, scalable backend services, and modern web interfaces. Code that ships: tested, observable, built to last.

Started with a simple console.log("Hello World"), now delivering production systems for Web2 platforms with strict uptime needs and Web3 protocols handling real on-chain value. I bring engineering rigor to dApps and modern tooling to enterprise systems.
