KEY_ACHIEVEMENTS

7-VPS proxy infrastructure

Architected and operate a distributed VLESS/XRay network serving ~30 active users in production with fallback routing and traffic-masking domain stubs.

Low-level network debugging

Diagnosed ISP-level 16KB packet filtering and Cloudflare restrictions during xhttp reverse proxy configuration — resolved via multi-day traffic analysis.

Incident response

Managed a production xhttp config failure: diagnosed the issue, broadcast to all users via Telegram, and restored service through domain migration with minimal downtime.

Infrastructure hardening

Tailscale mesh isolation, Nginx Basic Auth for admin panels, injection protection, and HTML traffic-masking stubs across all public domains.
