Summary

Blockchain and full-stack engineer with a builder-first mindset, focused on shipping production systems end-to-end. I architect smart contract stacks, data pipelines, and operational tooling that survive real traffic and real users. I move projects from concept to deployment with clear technical ownership across product, backend, and on-chain infrastructure.
