QA engineer building the mk-* MCP family for the full AI dev pipeline.
QA engineer by trade. I spend my days writing tests, and my evenings shipping the tools I wish those tests had.
Two parallel tracks:
- Open source — the
mk-*MCP family for the full AI dev pipeline (cards below). - Apps —
吃吃帖(location-based foodie community) and別扣我(driver's dashboard / speed-cam companion), both on iOS + Android.
Hobby is the same as work — build software, chase new tech, try to make QA simpler. Less "AI replaces testers" hype, more "the next round of tests is one prompt away."
Open-source MCP servers for the AI-driven dev pipeline. Each member owns one stage:
Idea → Plan → Spec → Code (your IDE) → Test → Coverage → Coach
mk-plan mk-spec your IDE mk-qa mk-spec both
The family wraps the rails; code-writing stays in your IDE. Three MCPs, one pipeline.

Two indie apps I built, maintain, and dogfood every day. Both iOS + Android.

Location-based foodie community — see what's good nearby, share what you found, follow what your friends loved.
