Martin Burian
Low-Level Developer & Security Explorer
Building systems from the ground up and breaking them down to understand how they work. Bridging embedded systems development with cybersecurity research—exploring both creation and exploitation.
Available for freelance embedded & software development projects
Developer. Hacker. Problem Solver.
I'm a Master's student at VUT Brno specializing in embedded systems, with a growing passion for cybersecurity. After spending nearly two years developing software for defense research, I returned to academics to deepen my understanding and explore new directions.
My journey started with low-level programming—building custom operating systems, writing device drivers, and developing firmware. Now I'm expanding into penetration testing and reverse engineering, currently working through the CPTS certification path on Hack The Box.
I believe the best security professionals understand systems deeply because they've built them. Whether I'm programming a smartwatch OS or finding vulnerabilities in code, I approach every challenge with curiosity and determination.

Education & Experience
Master's Student
Specializing in Embedded Systems with a growing focus on cybersecurity. Exploring the intersection of low-level development and offensive security through research and hands-on projects.
Software Developer
Developed software solutions for defense and military research applications. Worked on device drivers for Linux and low-level system programming. Left to pursue advanced education and explore new directions in cybersecurity.
Bachelor's Degree
Bachelor's in Computer Science. Thesis focused on low-level programming: developed an operating system for smartwatches built on FreeRTOS, implementing custom features and optimizations for wearable devices.
Projects I've Built
Smartwatch Operating System
Bachelor's thesis project: a custom smartwatch OS built on FreeRTOS for the LilyGo T-Watch S3. Since submitting, I've kept extending it — deep sleep with raise-to-wake, an on-watch settings interface, a reworked alarms UI, and a pass that fixed 20 real bugs (memory leaks, crashes, ISR-safety issues).

Custom Operating System
From-scratch OS development: Created a bootloader and implemented core OS functionality including memory allocation, basic process management, and hardware initialization. A deep dive into how operating systems work at the lowest level.

Smart Home System
Designed and built an integrated smart home automation system from scratch. Implemented custom protocols for device communication, sensor integration, and remote control capabilities.

Raspberry Pi Home Server
Self-hosted infrastructure on Raspberry Pi serving as a personal cloud, media server, and development environment. Configured services, security hardening, and automated backup systems.
OpenGL Renderer Engine
A layered C++20/OpenGL rendering engine built from scratch — App/Scene/Layer architecture, Blinn-Phong lighting, texture mapping, model loading, and a resource manager. Built as a clean, reusable foundation rather than a one-off demo; it now powers the Solitaire game below.

Solitaire
A fully playable Klondike Solitaire built on top of my own OpenGL renderer engine — drag-and-drop card logic, win detection, undo/reset, and a background best-first search solver that can check solvability or auto-finish a game in progress.
