From hands-on engineering to leading teams as PM and CTO, I've shipped products end-to-end. Now I build my own dreams — but I'm always open to jump on a cool project.
Who I Am
Ondrej Stolar
Full Stack Developer · Technical Leader · Entrepreneur
Engineer turned technical leader and entrepreneur. I've built products from the ground up, led multicultural cross-functional teams as PM and CTO, and shipped across startups and enterprises alike. From architecting scalable systems to making the hard calls on product direction — I've taken on all of it and learned something new every time.
I thrive under pressure, and that's when I do my best work. When deadlines are tight, stakes are high, and everyone else is looking for the exit — I'm the one rolling up my sleeves and finding the way through. Conflict resolution, problem solving, thinking outside the box — these aren't just buzzwords on my CV, they're how I operate daily. Now I channel all of that experience into my own ventures, solving real problems with clean code, sharp product thinking, and relentless positive energy. The word "can't" doesn't exist in my vocabulary. If there's a way, I'll find it. If there isn't, I'll build one.

What I Do
Full Stack Engineering
End-to-end product development — from Vue and React frontends to Node.js backends and REST APIs, all the way to production. I write clean, scalable code that ships fast and holds up long term.
Mobile & Cross-Platform
Native-quality apps built with Ionic, Capacitor, Swift, and Java — one codebase, every platform. Custom Capacitor plugins when the framework isn't enough. From concept to App Store, I deliver polished mobile experiences.
Technical Leadership
From roadmap to release — I lead cross-functional teams, define product strategy, and make the hard technical calls. Proven track record as PM and CTO across startups and enterprise environments.
Infrastructure & HA
Bare metal to cloud — Linux servers, Docker, Nginx, Hetzner, AWS. I design and manage high-availability clusters, networking, CI/CD pipelines, and monitoring stacks that keep things running 24/7.
