Robust Android VpnService/TUN networking with IP parsing, split tunneling, and TCP session tracking & stream reassembly (or tun2socksstyle userspace bridging).
Handson HTTP/HTTPS interception via local proxy, including TLS MITM, header parsing, and Cookie / SetCookie extraction & thirdparty classification.
Robust handson experience with Android VpnService, capturing full device traffic via TUN, including split tunneling and perapp allow/deny routing
Solid IP packet parsing (IPv4/IPv6) and flow identification from raw network traffic.
TCP state tracking and stream reassembly (handling sequence numbers, retransmissions, outoforder packets), or experience integrating tun2socksstyle userspace TCP/IP stacks
Ability to forward reassembled flows to a local intercepting HTTP(S) proxy (127.0.0.1) or upstream proxy VPN
HTTP header parsing with reliable extraction of Cookie / SetCookie headers and thirdparty cookie classification
