Full Stack Engineer
The person behind the code
I'm a full-stack engineer with 5+ years delivering production web products — fintech with secure authentication, complex SaaS platforms, and performance-focused e-commerce.
My main stack is React, Next.js, TypeScript, and Tailwind. I've built secure-session e-wallets, data-intensive portals, multi-tenant platforms, and legacy BI migrations to Spark + Superset.
I take end-to-end ownership: from spec to post-launch maintenance. Self-taught, proactive, and meticulous 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.
