What I'm looking for

I’m looking to build and ship production-grade Web3 and fintech products end-to-end—owning UX plus implementation, collaborating tightly with backend teams, and prioritizing performance, security, and real-time user experiences.

I’m a Full-Stack Developer and UI/UX Engineer with a track record of shipping production applications across Web3 and general software—6+ live deployed products spanning DeFi, NFT marketplaces, cross-chain messaging, event ticketing, AI assistants, and fintech wallets. I’m fluent across the stack, from React/Next.js frontends and Node.js/Express backends to PostgreSQL/MongoDB and Solana/Ethereum smart contracts.

I’m known for taking a product from idea to live MVP: owning both design and implementation, integrating real-time data flows, and delivering under real-world constraints. I’ve built and led UI pipelines (design systems, Core Web Vitals), implemented production security practices, and launched complete full-stack systems and integrations that stay responsive, secure, and usable in high-stakes moments.
