About me

I’m Bohdan Yatsenko, an IT student at SPŠE Úžlabině in Prague. I focus on networking and security: L2/L3, VLANs, routing, ACL/NAT, and basic hardening for Windows/Linux. I currently work as a Junior Technical Specialist (Hardware and Systems Integrations) at CzRobotics—building prototypes, testing hardware/software, and helping the team keep systems running.

I train with Cisco Packet Tracer and Wireshark, build small lab topologies, and rehearse typical incidents. On the side I build FireLog Insight—a small WPF/.NET tool for parsing Windows Firewall logs (filters, sortable table, charts, export).

For reverse engineering I use only Ghidra—just enough to understand program behavior and assess risk (no cracking or piracy).
