About
Fullstack engineer who builds and runs products end-to-end. I've worked on high-throughput enterprise backend systems and launched a production booking & e-commerce platform from scratch - covering architecture, payments, analytics and infrastructure.
- 01Built and operate a production e-commerce platform with booking, payments, analytics and admin - used by real customers every day.
- 02Designed reactive services processing 5B+ events/month at Škoda Auto - balancing architecture, performance and production stability.
- 03Own the full lifecycle: database design, APIs, frontend, deployment and monitoring.
- 04I make technical decisions and ship. I prefer building a working version over waiting for perfect specs.
How I Work
Ownership
I take responsibility for what I build - from the first commit to production monitoring.
Ship first
I prefer delivering a working version over endless discussions. Build, test, iterate.
Production mindset
Everything I design is meant to run in production - real users, real traffic, real consequences.
Technical decisions
I'm comfortable choosing architecture and trade-offs when needed.
