Adam Šitanc

Web developer and Linux sysadmin based in Prague. I build websites and infrastructure, and work on cybersecurity.

Bio

I spent six and a half years at Prusa Research, where besides technical work I took part in internal strategic and operational decisions, from financial models to choosing company systems.

Under the Unbound Solutions name I build websites for clients, run my own self-hosted infrastructure and develop a platform for race registration and timing. I like projects where code, servers and business sense meet. I start software with the process, not the code: first I find out how things work and where time is lost, and only then do I design the solution.

I work on cybersecurity, mainly server and email hardening and responsible vulnerability disclosure. That is also where reportable.cz came from.

Outside work I follow cycling, from both sides of the finish line. I organize races and run the timing too.
