I build decentralized applications and the
mobile experiences around them — bridging
blockchain protocols with the interfaces people actually use.

about.md
Full-Stack Software Developer with 15+ years shipping product across
the web, mobile, and blockchain. My career started in cross-platform
mobile — Ionic, Cordova, then React Native — building banking apps,
smartwatch interfaces, and even credit-card machine UIs before most
teams had one mobile dev. Today I specialize in the hand-off between
Web3 protocols and their users: smart contracts, cross-chain
bridges, and DeFi dApps on Ethereum, Aeternity, and Cosmos, with
mobile-first interfaces that make decentralized tools feel native.
React, TypeScript, Solidity, Sophia, Wagmi, Ethers — and a strong
opinion that good Web3 is invisible Web3.
