Systems & Network Infrastructure Engineer
Specializing in Low-Latency Protocols, User-Space Networking, and Distributed Proxy Architectures.
- Transport & Proxy Protocols: In-depth implementation and tuning of VLESS, Reality (TLS 1.3 Camouflage), WireGuard, Cloudflare WARP, and multiplexed tunnels.
- Network Stack & Kernel Interfaces: Virtual network device management (
TUN/TAP), User-space network stacks (gVisor netstack), Packet routing, and NAT configuration. - Low-Latency Systems Design: Engineering application-layer protocols over persistent full-duplex WebSockets (sub-5ms execution latency) with strict access-control tiers.
- Client-to-Core Integration: Orchestrating background network processes (
sing-box core), IPC via local loopback sockets, and cross-platform native hooks (Android VpnService). - Linux Systems & Reliability: Kernel parameter optimization (
sysctl), TCP Congestion Control tuning, MTU path discovery, resource containment (cgroups/OOM mitigation), and CI/CD cross-compilation.

Ultra-fast, zero-overhead agent-to-server infrastructure control protocol.
- Engineered as an application-layer protocol running over persistent WebSockets, eliminating the latency and memory overhead of pseudo-terminal (PTY/TTY) emulation.
- Achieves sub-5ms deterministic command execution latency with an integrated 3-tier cryptographic privilege validation model.
Zero-dependency tunnel management panel & high-throughput multiplexing core.
- Architected for resilient, censorship-resistant networking with native connection pooling and multiplexing.
- Implemented with zero external dependencies to ensure minimal attack surface and deterministic runtime performance on minimal VPS footprints.
Cross-platform, high-throughput network tunnel client.
- Orchestrates headless
sing-boxcores through local loopback interfaces with automated lifecycle monitoring and error recovery. - Implements direct Android
VpnServiceintegration for transparent Layer 3 full-system TUN routing without root privileges. - Resolves upstream race conditions across local gRPC IPC channels and network state transitions.
Multi-platform environment recovery & state sanitation utility for developer runtimes (115+ GitHub Stars).
- Cross-platform automation (PowerShell/Bash) for cleaning orphaned state, managing browser/IDE session databases, and automated environment resets.
Modular multi-agent automation ecosystem for large-scale technical workflows.
- Contains 16 operational sub-skills, 10 deterministic agent personas, 89 execution scripts, and 160+ structured tool-calling specifications.
