Built three network analysis tools over the past year. FOSS.

netgrep. Rust packet analyzer. TLS decryption, stream reassembly, interactive TUI.
termshark. Go. Forked the terminal Wireshark UI, refactored, added a web interface.
wiregraph. Real-time network traffic visualizer. Rust backend reuses netgrep's parser. Embedded web dashboard with connection matrix, protocol breakdown, activity.
