Hi, I’m Piotr — a software engineer who lives deep in the Apple platforms, building low-level macOS software: system extensions, privileged helpers, and security and input internals.

This little corner of space is where I jot things down. Here’s what you’ll find:

• Blog — notes and the occasional tutorial on Apple-platform and systems development.
• Work — a tour of projects I’ve built, from GOG Galaxy to endpoint security at WithSecure.
• Resume — the full timeline, if you’re curious.

Say hello

The fastest way to reach me is email — you’ll find my address, plus links to LinkedIn, X and GitHub, in the Contact box in the sidebar.

More to come — for now, thanks for dropping by. 🚀
