About me

I work where hardware meets software.

I'm a Computer Engineering student at the Faculty of Management and Informatics, University of Žilina, deeply interested in embedded software development and low-level programming. I've programmed firmware for microcontrollers such as the Atmel AVR, ESP32 and Raspberry Pi Pico — handling GPIO, communication protocols and peripherals, and bridging the gap between the chip and the application layer.

Alongside embedded work I've built experience in C/C++, assembly, electronics and measurement tools, plus web technologies and networking. I like projects that force me to understand the full stack, from how a register is set to how the UI renders the data it produces.
