About me

I'm a full-stack developer who loves turning messy problems into clean, automated and scalable solutions.
After leading entire product development and backend teams at a fast-paced startup, I've learned that great code isn't just about writing - it's about listening to what users actually need.
Today I build systems in Go and Node.js that quietly handle millions of requests without breaking a sweat, while my inner tinkerer is constantly automating life's little frustrations.
