Full-stack maker building things at the edge — deploying LLMs on phones, flashing FPGA boards, and keeping servers running in my room.

01. About

Self-taught maker from Henan, China. I build things at the edge — deploying LLMs on phones, automating daily tasks with scripts, flashing FPGA boards, and keeping servers running in my room. When I'm not coding, I'm making tech tutorials on Bilibili.

My server runs Ubuntu 22.04 with Nginx, Node v20, and Python 3.10. I host a SearXNG instance and share AI models on HuggingFace. The goal is simple: make powerful tools accessible, one project at a time.
