Computer science graduate from FIT VUT Brno, continuing into a master's in cybersecurity. Security-focused, with work in embedded systems and self-hosted infrastructure.
I finished the Bachelor of Information Technology programme at FIT VUT Brno in June 2026, and I'm continuing at the same faculty in the master's programme with a cybersecurity specialisation, starting September 2026. Before that I studied at Gymnázium Ladislava Novomeského in Senica with a computer science specialisation.
Most of my work is low-level: C and C++, networking down to the packet, and the Linux infrastructure underneath it. I run a self-hosted setup at home, which is where I try things out.
Open to internships and working student roles. My inbox is the best way to reach me, or you can download my CV.
A client/server tool in C that transfers files hidden inside ICMP and ICMPv6 Echo packets. Files are AES-encrypted over raw sockets and reassembled on the receiving end using a custom framing protocol for fragmentation and integrity.

Two-stage implementation of a small object-oriented language. Python front-end parses the source using Lark and emits an XML AST after static semantic checks. A PHP back-end interpreter walks the tree with classes, methods, blocks, and full message-passing semantics.

Embedded heart-rate monitor using photoplethysmography on an ESP32. ADC sampling runs on a hardware timer, the signal is Kalman-filtered for noise reduction, and a threshold-crossing algorithm detects beats. FreeRTOS semaphores coordinate the ISR with the processing thread.
