About

I'm a CTO who leads from the codebase — setting technical direction, building engineering culture, and still rolling up my sleeves when it matters. My playbook covers smart contract architecture, cloud infrastructure, data pipelines, and the team processes that hold it all together. I've taken products from first commit to scale in Fintech, Edutech, and decentralized finance, building lean teams that ship fast and stay reliable.
