What I'm looking for

I’m looking for a role where I can build decentralized products end-to-end—smart contracts, secure full-stack features, and smooth UX—while working with a team that values security, performance, and pragmatic innovation.

I’m a blockchain engineer who loves turning complex protocols into products people can actually use. I founded a decentralized document-signing platform on Sui, where I won 1st place at Sui Overflow 2025 among 3,000+ developers.

I build core on-chain logic in Move and Solidity, then connect it to a hardened full-stack experience. For Sui, I authored smart contracts for multi-party agreement lifecycles with cryptographic audit trails, integrated Walrus storage to cut costs ~67% vs. incumbents, and delivered a gasless UX using sponsored transactions plus zkLogin.

I also ship end-to-end features and automation: React/Vite SPAs with drag-and-drop signing, Node.js/Express APIs, PostgreSQL, and encryption (AES-256-GCM) with security hardening (CSP, HSTS, rate limiting). In previous work, I built an oracle-backed prediction market on Arbitrum Sepolia with Chainlink feeds and automated resolution/indexer updates; as a freelancer, I delivered Web3-enabled frontends and real-world platforms using React and FastAPI.
