Tunnely · tunnely.org
  • Built a full-stack Virtual Private Network (VPN) platform in Rust with a Tauri + Solid.js desktop client, distributed relay server infrastructure spanning 10 nodes across North America, Europe, APAC, and South America, and a Next.js marketing site with Stripe billing and PostgreSQL-backed Supabase database
  • Implemented WireGuard-based encrypted tunneling (ChaCha20-Poly1305, Curve25519) using a userspace boringtun stack with async TUN device management
  • Designed a multi-relay mesh network with automatic peer discovery, latency probing, and optimal path computation for multi-hop routing
  • Engineered channel bonding system aggregating multiple network interfaces (WiFi + Ethernet + Cellular) with custom binary protocol, packet reordering, and three bonding modes
  • Developed QUIC obfuscation layer wrapping WireGuard traffic as HTTPS/HTTP3 to bypass ISP-level VPN detection, plus a man-in-the-middle (MITM) HTTPS proxy for client-side ad/tracker blocking
