I build software close to the metal.

Future software engineer with a focus on low-level programming, systems, and performance. I turn hard problems into clean, working code — and I like sharing what I build.

A few things I've built and am proud to show off.

Flagship

BrebOS

A hand-built operating system for x86, written mostly in C++ — with its own bootloader, kernel, GCC cross-toolchain, C/C++ standard library, network stack, and POSIX-subset shell.

  • C++
  • x86 Assembly
  • Custom GCC Toolchain
  • QEMU

Sudoku OCR

A C++/Qt6 app that detects, reads, and solves a Sudoku from a photo, with a hand-written computer-vision pipeline and a neural network for digit recognition — no OpenCV involved.

  • C++
  • Qt6
  • Computer Vision
  • Neural Networks

brebhome

A self-hosted homelab running over a dozen Docker Compose services behind an nginx + Authentik SSO gate — media, file sync, a searchable photo library, and automation that watches over itself.

  • Docker Compose
  • nginx
  • Authentik
  • Cloudflare Tunnel

Algorithms Visualization

A Unity app that visualizes 14 classic algorithms across four tools — Sudoku solving, sorting, pathfinding, and prime sieves — built in high school and running just as well on Android.

  • C#
  • Unity
  • Windows
  • Android

Let's build something together.

Have a project in mind, an internship offer, or just want to talk low-level systems? I'd love to hear from you.
