Backend systems · local-first AI tools · evaluable product loops
Toronto · Taipei
I am a backend engineer working around distributed systems, internal tools, and AI workflows.
Lately I have been interested in:
- local-first tools that do not leak private user data
- AI systems with visible prompts, costs, latency, and eval results
- writing technical notes that normal people can actually read
- small products that are boring enough to keep using
| Project | What it shows |
|---|---|
| 12wy-tracker | Local-first Tauri desktop app for 12 Week Year execution, BYOK/Ollama AI coaching, prompt logs, budget limits, eval artifacts |
| AI evaluation loop | Prompt versioning, fixed cases, rubric scoring, usage/cost/latency tracking, inspectable prompt history |
| Backend practice | Go, Python, event-driven systems, data stores, reliability tradeoffs |
- Building agentic AI workflows that fit real engineering teams.
- Writing at Zoe Site about AI, backend systems, and plain-language tech.
- Studying system design, evaluation, and how engineers can work better with AI.
