Hello! I'm NeoJ — on GitHub as @uk0 (a.k.a. 下水鱼 / Cumulonaut). A networking & infrastructure engineer and a polyglot open-source builder. I spend most of my time on NAT traversal / TCP acceleration, AI tooling & MCP servers, and cross-platform apps, and I enjoy breathing new life into old servers and retro hardware.
Featured Projects
A few of my open-source projects on github.com/uk0 (150+ public repos):
| Repository | Description | Tech |
|---|---|---|
| lotspeed ★425 | TCP network accelerator — a modern homage to “锐速 (ServerSpeeder)”, with kernel-module support. | Shell / C |
| stun_max ★83 | P2P TCP tunnel with STUN hole-punching and automatic relay fallback; zero-config, cross-platform GUI + CLI. | Go |
| web-search-fast ★55 | A fast local web-search MCP server with clustered deployment — feeds real-time search to LLMs. | Python |
| file_encryption ★43 | Encrypt small (<1 GB) files with the filename embedded; self-extracting, three-platform support. | Rust |
| telethon_get_media ★225 | Telegram media downloader for group files and videos. | Python |
| silk | Silk — a cross-platform Go UI framework & visual designer. | Go |
→ See all projects at github.com/uk0.
