01 — About

Clear code.
Honest delivery.

Over the past eight years I've helped teams at Citi, Mphasis, Terra.do and MVIX modernize backend systems, move to the cloud, and ship features customers actually use.

Now I freelance — working directly with founders and product teams on the work that matters most: architecture, APIs, infrastructure, performance. I keep communication simple, code clean, and the process transparent from kickoff to deploy.
