About

Independent systems-focused engineer working on task-based and project-based network analysis and modification work.

My work centers on examining and modifying existing VPN and tunneling implementations to understand and validate how they behave across real ISP environments, especially under filtering, blocking, and non-ideal mobile network conditions.

I routinely work with large open-source codebases such as OpenVPN, WireGuard, SoftEther, and Psiphon, focusing on handshake flow, SNI placement, CDN-based fronting, and traffic visibility rather than application UI or product features.

My approach is empirical and hands-on: packet-level inspection (TLS / HTTP / WebSocket), controlled test setups, and direct validation on live networks using tools like Wireshark.

I engage selectively in short-term, scoped technical work where clear observation, practical modification, and explanation of real network behavior are required. I am not seeking full-time roles.
