Fullstack Engineer

Python & FastAPI on the backend, Next.js on the front. I build things end to end and care that they hold up in production.

About

I take ideas from concept to production. One developer responsible for the full picture: architecture, implementation, deployment. No handoffs, no gaps, one person who actually owns the outcome.

I ask the right questions early, push back when the technical approach doesn't fit the business goal, and communicate without the technical fog.

I'm Leo Proger. I started shipping real software at 13, building a real-time messenger solo, and haven't stopped since.

Python and FastAPI on the backend, Next.js and Tailwind on the frontend. Solid Java and Spring experience in the background, though my focus has moved. Docker, CI/CD, Linux: everything it takes to get the product running in front of real users.

Open for commercial work. Got an idea that needs to become a real product? Reach out.
