Hi, I'm Grzegorz

Software engineer with a passion for both low-level systems programming and modern web development. I work across the full stack, from writing C and Rust for embedded systems to building web applications with Vue.js and Nuxt.

Proud contributor to open source projects including FreeBSD and Buildroot. I enjoy working with real-time operating systems like Zephyr, container technologies, and enterprise databases.
