Network and security developer. I design and build VPN cores and firewall evasion systems, along with Android, iOS, and cross-platform apps built on top of them.
Firewall detection & evasion, network protocol engineering, and VPN core development — building the systems that keep traffic running under restricted networks. Broader background in network infrastructure and cybersecurity: routing, packet analysis, and hardening systems against real-world attacks.
MikroTik / RouterOS configuration, routing & firewall rules, traffic analysis with Wireshark, network scanning with Nmap, and penetration testing on Kali Linux with Metasploit, guided by OWASP practices.
