Full-Stack Web3 Engineer specializing in React, Node.js, and frontend architecture, with deep experience building DeFi platforms, crypto custody systems, and cross-chain wallet products.
I enjoy owning systems end-to-end, solving ambiguous problems independently, and leveraging AI to deliver reliable, production-grade Web3 experiences.
