Who I Am

About Me

I'm a senior engineer who ships fast and gets the architecture right first time. I've spent 8+ years building real products — React Native apps, iOS/Swift codebases, full-stack platforms on AWS, and enterprise systems for companies ranging from NSE-listed firms to funded startups.

I've worked across 7 industries. Each taught me something different — HIPAA-grade data handling in healthcare, compliance flows in fintech, offline-first architecture for enterprise, DRM and adaptive bitrate for OTT. I don't just code to spec; I ask why.

I was a founding member of KozyClan — built it end-to-end: mobile app, backend APIs, admin CMS, Razorpay escrow, GST invoicing, KYC workflows. That product ownership is what I bring to every engagement.
