Hi, I'm Qing Li 👋

I build self-hosted infrastructure and full-stack developer tools — mostly in Go, Python, and TypeScript, with side quests in CUDA, firmware, and Android bring-up.

What I build

  • 🧠 LLM infrastructure — API gateways, multi-agent pipeline orchestration, observability
  • 📡 Self-hosted services — notification hubs, media streaming, home-lab tooling
  • ⚡ Systems & parallel computing — CUDA kernels, MPI/OpenMP, OpenWrt firmware, AOSP device trees

Featured projects

Project What it is Stack
prism Self-hosted LLM proxy gateway with multi-provider routing, load balancing, and observability Go
signaldeck Self-hosted "mini-Jenkins" that runs YAML-defined multi-agent LLM pipelines Python · React
herald Notification hub: JSON ingest over HTTP, rule-based filtering, delivery to Bark / ntfy / MQTT / Gotify Python · React
last-whisper Dictation training platform — FastAPI backend, React PWA frontend Python · React
galaxy-pair-cuda CUDA kernels for fast two-point galaxy angular correlation CUDA
closure-table-spring-boot-demo Folder trees with the closure-table pattern, Spring Boot + MyBatis Java
immortalwrt-firmware-builder Reproducible ImmortalWrt firmware builds — seed configs, Docker env, CI workflow Docker · CI

Toolbox

Go Python TypeScript Java Rust C/C++ CUDA · FastAPI Spring Boot React Next.js · PostgreSQL SQLite · Docker GitHub Actions Cloudflare Workers
