How I Work
I'm a software architect and security engineer based in Gdańsk. I build backend systems, audit applications for vulnerabilities, and work on AI tooling. Outside of that — gym, carpentry, and too much time thinking about cars.
› Secure by default, not bolted on.
Security gets designed into the architecture, not patched on after the fact.
› Production, not demos.
AI and agentic tooling has to behave reliably in production — not just impress in a demo.
› Physical work keeps the abstractions honest.
Carpentry and DIY are the counterweight — you can't abstract your way out of a bad cut or a loose joint.
Software Architecture & AppSec
Most of my work lives in backend systems — designing services that are reliable, secure by default, and easy to reason about. I also do application security audits and penetration testing, which means I spend a fair amount of time thinking about how things break, not just how they should work.
AI & Agentic Systems
I've been building AI-powered tools and agentic workflows for a while now. Mostly focused on practical applications — automating complex processes, integrating LLMs into existing systems, and making sure they behave reliably in production rather than just in demos.
Health & Training
I take training and recovery seriously — gym, sleep, nutrition. Not an obsession, just a baseline. It's hard to do good work when the hardware isn't running well.
Carpentry & DIY Projects
I do carpentry and various DIY projects in my spare time. There's something grounding about building physical things — you can't abstract your way out of a bad cut or a loose joint.
