Adam Ourednik

Building websites, applications, and hardware that make sense.

I am a developer from Czechia focused on full-stack web development, reliable backend engineering, and hardware integrations. I believe clean code should solve real problems – whether modern websites, web applications, or programming microcontrollers and relay circuits.

I work directly with you, without agency bureaucracy or unnecessary middlemen. I prefer a minimalist, precise style and clear architecture where visitors and users immediately find what they need.
