Hi 👋, I’m Mikołaj

I like knowing how things work underneath - whether that’s userspace programs, operating systems, bootloaders, or the silicon itself. I write C and C++ for a living and for fun.

On my own time I build things from scratch to understand them fully:

• A Vulkan game engine with 13+ abstraction modules covering the full rendering pipeline
• A custom x86 operating system with a 2-stage real-mode bootloader and FAT12 filesystem
• A BLE-connected e-paper wearable on ESP32 with custom binary protocol and image dithering
• A game console engine running a software 3D rasterizer on a microcontroller
• A multithreaded tool that converts video into colored animated ASCII art in real time

I contribute upstream too. My fix to Intel’s Cryptography Primitives Library cut ~10% CPU time and ~50% instructions in multithreaded hashing workloads. My SliderWithCallback addition to FTXUI was merged by the maintainer. I’ve been published in PagedOut! #6, Gynvael Coldwind’s technical zine.

I started coding at 11, did my first paid gig at 13, competed nationally in C++ at 17, moved cities alone at 18 for my first full-time job, and reached senior at 19. I got here by being stubborn - I gave up on programming three times before it stuck.

Interested in: OS internals, embedded Linux, real-time rendering, game engines, microcontrollers, security, and anything where the answer to “why is this slow” matters.
