My story

About me

I've always been curious about how things work—not just the finished product, but the systems underneath. That curiosity eventually became a career, and for the past 15 years I've been building software across the stack, from backend services to modern web applications, wherever the problem happens to live.

What keeps me interested isn't a particular language or framework. It's figuring out why something feels slow, complicated, or fragile, then finding a simpler way to build it. I enjoy turning messy ideas into reliable systems, whether that's shipping products, automating workflows, or exploring how AI can make everyday tools genuinely more useful.

Originally from Romania, I've spent the last few years traveling the world while continuing to build software remotely. Along the way I've picked up interests in photography, travel, automation, and creating products that solve problems I'd want solved myself.

I don't feel like I've "arrived." Technology moves too quickly for that. There's always another tool to explore, another architecture to rethink, or another idea worth building. That's probably what I enjoy most about this industry.
