Physiatrist (PM&R) in Hualien, Taiwan — rebuilding medicine, learning, and life with evidence + engineering.
I'm a rehabilitation physician who codes. My favorite problems live at the intersection of clinical medicine × evidence-based practice × AI knowledge workflows × self-hosting — and I share the whole process in public, failed experiments included.
- 🏥 By day — physiatrist at Hualien Tzu Chi Hospital: musculoskeletal ultrasound, manual therapy, sports medicine
- 🔬 By training — evidence-based medicine: meta-analysis, critical appraisal, national health-insurance database research
- 🤖 By night — building AI-powered study & research pipelines with Claude Code, Obsidian, and a homelab
Everything here is exhaust from my real daily workflow — I build tools to use them, then open-source what survives.
| Project | What it does |
|---|---|
| 📡 paper-radar | Personal literature radar — journal/PubMed feeds → interest-scored triage site → straight into your notes. Discovery end of my paper pipeline. |
| ⬇️ paper-fetch | Publisher-aware full-text fetcher — DOI in, PDF out, via open access → publisher TDM APIs → your own institutional proxy. Download end of the pipeline. |
| 📖 paper-review-and-digest | Claude Code skills for journal-club-grade paper appraisal (deterministic GRADE + CrossRef gate) and fast content digest. Reading end of the pipeline. |
| 🎙️ asr-benchmark | Score speech-recognition models on your own audio with no ground-truth transcript — build a lexicon from your field's literature, then measure real terms captured vs hallucinated. |
| 🔍 vault-search | Local-first semantic search, related notes & RAG chat for Obsidian — plugin + MCP server over one LanceDB + Ollama index. |
| 📝 exam-practice | Self-hostable past-exam practice platform driven by FSRS spaced repetition, built for medical board prep. |
I write (mostly in Traditional Chinese) about rehab medicine, AI knowledge workflows, and self-hosting at drpwchen.com — how each tool above was built, what broke along the way, and what I'd do differently.
If any of these tools saved you some time, you can buy me a boba 🧋 — it keeps the homelab humming.
