About

How I work

Efficiently — always

No over-engineering. Clean, maintainable code that ships on time and holds up under scale.

Design-fluent

9 years alongside designers taught me to bridge the gap — I understand both sides of the screen.

Full-stack when needed

NestJS, Firebase, MySQL — enough backend to build end-to-end without waiting on anyone.

Always learning

Tech evolves fast. I stay ahead — whether it's a new framework, pattern, or tool worth mastering.

Years turning requirements into experiences people actually enjoy using.
