🎓 I'm a cybersecurity student at Warsaw University of Technology, currently in my 4th semester. I enjoy working close to the metal — whether it's backend development, system-level analysis, or FPGA design.

At university, I’m involved in practical cybersecurity labs, signal processing, and networking exercises — working with protocols like BGP, RIP, SNMP, and network emulation tools like Mininet. I combine that knowledge with hands-on projects in both software and hardware.

Verilog-based system for detecting abnormal traffic bursts. Uses CRC hashing, frequency thresholds, and signal analysis. Testbench simulation + waveform tracing via GTKWave. Python model also included.

RESTful backend with real-time logic, authentication, and database persistence. Used in backend training for CRUD operations on coaches and sessions.

Network-ready Java chess with save/load, GUI (Swing), and AI logic. Built as a side project to explore OOP + game state architecture.

Designed virtual topologies with multiple hosts and switches. Configured delays, bandwidth, queue sizes, and ran tests using iperf, pingall, and HTTP server clients. Explored routing behavior and packet loss under stress.

Python script using OpenAI’s GPT to intelligently sort incoming JSON-based emails into relevant folders. Smart automation meets actual usefulness.

• Cybersecurity (network protocols, OSINT, detection strategies)
• Digital systems and embedded logic
• Backend services, APIs, and automation
• Legal aspects of cybersecurity, monetary policy & economics
• Tools that reduce friction and expose what’s under the hood

• I believe security should be engineered, not patched.
• I enjoy debugging logic and signals more than most.
• I treat tools like dumpvars and iperf as everyday essentials.
• If I don’t understand how it works, I dig until I do.
