Computer Engineer — systems, cybersecurity, applied AI, and product software.
Kraków, Poland · Founder, ARNOVA Group · Open to engineering roles
I design and ship software that has to survive contact with the real world: booking sites, mobile coaches, traffic desks, threat-intelligence platforms, study tools, and private vaults.
Trained in software systems and cybersecurity (Wrocław, 2022–2025). Founder of ARNOVA Group. I care about architecture you can explain, interfaces people can finish using, and security that is designed in — not bolted on.
