What I'm looking for

I’m looking to build and ship end-to-end blockchain and fintech products in a fast-moving team—owning architecture, smart contracts, and backend systems, with strong CI/CD and reliability. Open to roles where impact and autonomy matter.

I’m a 7+ years full-stack engineer and Fintech & Web3 specialist with deep experience across EVM and Bitcoin-style UTXO chains. As a founding engineer twice, I’ve learned how to own outcomes end-to-end in fast-moving environments—turning architecture into production systems that scale.

Most recently, I built and shipped the first token/NFT cross-chain bridge on Kaspa (Kaspa/Kasplex), owning the end-to-end delivery: onchain event listeners, RabbitMQ transaction queuing, failure recovery, and production CI/CD—securing $10M+ in assets (vault address). I also deployed mainnet Solidity contracts with burn/mint flows, multi-sig security, and automated governance for ERC-20 deployment, and contributed to an open-source Kaspa mining pool with high-volume monitoring using structured Datadog metrics plus file-based logging.
