Full-stack Developer & Cybersecurity Engineer — Slovakia
I build things,
then I try to break them.
I'm Adam. I design and ship full-stack applications, then put on the other hat — penetration testing, hardening, and threat modeling — to make sure they hold up.

About
Hi — I'm Adam, a full-stack developer and cybersecurity engineer from Slovakia. I design and secure websites, automate infrastructure, and perform penetration testing and system hardening. I like working across the whole stack: writing the application, deploying and defending the servers it runs on, and stress-testing the result until it's genuinely hard to break.
