Builder across AI infrastructure, full-stack web, and self-hosted systems. I like turning powerful tooling into something tech agnostic people love to use.
- AI orchestration & agents — self-hosted agent harnesses with tool-calling (MCP), scheduling, and messaging gateways; multi-agent setups that route each task to the right-sized model. Most of my assistants live in WhatsApp and Discord, so non-technical people reach them where they already are.
- Retrieval / RAG — production systems that parse thousands of technical documents, embed them, and answer with citations traceable to the source.
- Full-stack products — Next.js / TypeScript / React on Supabase + Postgres, shipped on Vercel, plus the data plumbing behind them: scrapers, ingestion, realtime, offline-first sync.
- Self-hosted infrastructure — homelab NUCs on Ubuntu running Docker and local models (Ollama); background workers and cron across Windows, macOS, and Linux.
- Community & mission work — coordination tools, on-chain reciprocity, and small-business systems for the people and orgs I work with.
Exploring computational tooling for bioelectricity research — in-silico modeling and literature synthesis.
Most of what I build is client, private, or self-hosted — so this profile is lighter than my actual output, and the contribution graph tells more of the story than the pinned repos.
- Office of the Three Sisters — o3s.foundation — community coordination + on-chain reciprocity (Optimism, account abstraction, IPFS)
- cantonese-kin — a Cantonese kinship-terms learning app
