Available for freelance firmware projects
Embedded developer specializing in ESP32, RP2040/RP2350, FreeRTOS and Linux device drivers, with a security background that shapes how I build.
What I do
From dev-board prototype to stable production firmware on ESP32, RP2040/RP2350 and FreeRTOS.
Getting new hardware talking: peripherals, sensors and Linux kernel drivers, written from the datasheet.
Deep sleep, wake strategies and measured current draw, for devices that need to last on a battery.
Firmware reviewed and hardened by someone trained to attack it.
How I work
We talk through your product, the problem and what "done" means.
I audit the code or hardware and give you a clear plan and quote. Low risk for you.
You always know where the project stands, with no surprises at the end.
Documented code and notes, so your team can maintain it after me.
Selected work
Challenge: a complete wearable OS for the LilyGo T-Watch S3, under real power and memory constraints.
What I did: built the OS on FreeRTOS as my bachelor's thesis, then kept extending it with deep sleep and raise-to-wake, an on-watch settings interface and a reworked alarms UI.
Result: a dedicated reliability pass fixed 20 real bugs, including memory leaks, crashes and ISR-safety issues.
View on GitHubChallenge: safe remote control of an autonomous vehicle over the internet, at Bringauto.
What I did: built the WebRTC-based teleoperation system. Most of my work was focused on audio, webRTC and general reliability of the data transfer
Result: Video latency over LTE under 50ms on average, Audio working end to end, including full HD video on 30FPS+
Bootloader, memory allocation, process management and hardware initialization, written from scratch in C and assembly for x86.

A C++20 rendering engine built directly on the graphics API, with no engine or framework: layered App/Scene/Layer architecture, a custom resource manager, model loading and manually implemented Blinn-Phong lighting.
To prove it end to end, I built a complete Klondike Solitaire on top of it, including drag-and-drop, undo and a best-first search solver that can check solvability or finish a game automatically.

Home automation built from scratch on Raspberry Pi, with custom protocols for device communication, sensor integration and remote control. The system was generalized so that you could define a json with specific parameters and flash any ESP32/8266.

About
I spent two years writing Linux drivers and low-level software for defense research, then built teleoperation for an autonomous vehicle at Bringauto. Now I'm finishing a Master's in embedded systems at VUT Brno.
I also train in offensive security on the Hack The Box CPTS path. Knowing how devices get attacked changes how I build them.
