Full-stack developer.
Ships in production.

I build web and mobile applications that solve real problems — not just side projects.

From multilingual systems to APIs and mobile apps, I enjoy working across the full stack and turning complex ideas into functional, scalable solutions.

Before becoming a full-time developer, I worked with automation systems and handled real-time issues — which taught me how to stay calm when things break (because they always do).

Now, I focus on building systems that are reliable, scalable, and actually useful.
