About Me
Software / Cloud DevSecOps Engineer
For the past five years I've been hooked on Linux from Scratch (LFS) and Beyond Linux from Scratch (BLFS). At first, the goal was to manually build my own Linux distribution by following the LFS and BLFS documentation. That project evolved over time — I now have Jenkins pipelines that automate the build of my distribution in a few hours, featuring a Hyprland frontend. I run this LFS/BLFS-based system natively and plan to use it as my main platform for future Linux kernel development.
Goals
I'm currently focused on gaining a deeper understanding of the Linux kernel — not only the code itself, but also the community workflow, review process, and contribution practices that surround it. My long-term goal is to start contributing meaningfully to the Linux kernel project while documenting what I learn along the way.
System Details
Base/Native: LFS w/pieces of BLFS
Window Manager: Hyprland
Tools: GDB, QEMU, Vim, Git, Mutt, Procmail, Fetchmail, and Sendmail
Interests
Linux: LFS/BLFS; Hyprland; Linux Kernel: development, process/workflow, debugging, internals, security
Cloud: Infrastructure, security
DevSecOps: practices
Other: Automated build systems, Opensource
