About Me

I'm a senior software engineer with 5+ years of experience shipping production applications across hospitality, blockchain, and e-commerce domains. I own the full stack — from database schema to pixel-perfect UI.

Currently at Majestic Vacation Management, I've architected platforms handling 1,500+ bookings/month and built crypto infrastructure tracking $250K+ in transactions. Previously at Devslane, I designed multi-tenant systems, integrated blockchain smart contracts, and led performance initiatives that halved API response times.

I work best at the intersection of clean architecture and tangible product impact. Whether it's an NPM package, a real-time dashboard, or a multi-chain wallet system — I build it end to end. I lean heavily on spec-driven AI workflows with Claude, turning product requirements into implementation plans backed by rigorous code review and validation.

“Shipping fast isn't reckless — it's a skill.”
