Who I Am

I'm a full-stack engineer with 5+ years delivering production web products for the US market — fintech with secure authentication, regulated multi-state SaaS, and performance-focused e-commerce platforms.

My main stack is React, Next.js, TypeScript, and Tailwind. I've built secure-session e-wallets, data-intensive portals, jurisdiction-configurable platforms, and legacy BI migrations to Spark + Superset.

I take end-to-end ownership: from spec to post-launch maintenance. Self-taught, proactive, and obsessive about DX, product quality, and accessibility.

Outside of work, I practice Shotokan Karate (2nd Dan), learn about technology, and play exploration and fantasy titles. I believe that good code and martial arts share clarity, discipline, and constant improvement.
