About

About me

I'm a backend engineer focused on microservice architectures and developer tooling. With 13 years of experience, I've spent recent years building backend systems and working across a range of technologies, while diving deep into distributed architecture and performance optimization.

Lately I've been diving into AI — reading about how these systems work, exploring what they can do, and getting hands-on by building things with Claude. I like learning by doing, turning curiosity into small projects, and figuring out how good tooling can quietly make everyday work easier.
