1. Core Development: Maintain and extend a high-performance forwarding engine based on sing-box or Xray-core.

2. Protocol Innovation: Implement and optimize cutting-edge network protocols, including REALITY, Hysteria2, TUIC, and custom gRPC/TLS obfuscation layers.

3. Network Optimization: Tune TCP/UDP throughput and congestion control algorithms (e.g., BBR, QUIC, PCC) for high-packet-loss scenarios.

4. Anti-Censorship Technologies: Research and develop solutions to bypass deep packet inspection (DPI) and mitigate TLS fingerprinting (uTLS).

1. Programming Languages: Proficient in Go (Golang) or Rust.

2. Low-Level Networking Knowledge: Deep understanding of the OSI seven-layer model, the TCP/IP protocol stack, and Linux kernel networking mechanisms (TUN/TAP, iptables/nftables).

3. Protocol Implementation Experience: Hands-on experience with TLS 1.3 handshake, QUIC, and HTTP/3.

4. Project Track Record: Consistent code contributions to network open-source projects (e.g., sing-box, Xray, V2Ray, Clash, or Shadowsocks).

5. Problem-Solving Ability: Skilled at optimizing global routing strategies and managing complex BGP/Anycast network architectures.
