I'm interested in electronics at the register and hardware level: microcontrollers, digital logic, PCB design. Looking for my first role in embedded - I don't mind when something doesn't work on the first try.
Who I am
I'm a third-year Applied Computer Science student at the Faculty of Electrical Engineering, Warsaw University of Technology, specializing in Computer Engineering. I'm interested in embedded systems and IoT - from circuit design in Proteus, through programming microcontrollers (ESP32, STM32, MSP430), to working with digital logic and communication protocols.
Outside of coursework I build my own hardware and software projects - some succeed, some teach more by not working out. In parallel, I develop 2D games in Unity on commission, which taught me how to work with a real client and ship on time.
What I've been working on
DC Motor Speed Controller - Discrete Logic
IN PROGRESSA DC motor speed controller built entirely from discrete logic, no microcontroller - designed and simulated in Proteus, assembled on my own PCB. Currently debugging a fault on the board; the individual blocks (555, 4066) test correctly in isolation on breadboard.

DONEA DIY infrared TV remote built around an ATtiny13, controlling 6 buttons through a single ADC pin via a resistor ladder network, with the IR signal replayed from a captured original remote code compressed into indexed timings to fit within 1KB of flash. The enclosure was 3D-printed and the PCB was hand-etched using sodium persulfate.

COURSEWORKA set of assembly programs written for coursework: ADC12 handling, timer interrupts, driving an LCD in 4-bit mode, and a binary-to-BCD converter. Direct register-level work, no abstraction layers.
