About

Writing code is fast now. Validating it isn’t. A change takes 10 minutes to write. Validation takes 2–3× longer. Not because testing is hard. Because engineers have to figure out: → What does this PR actually affect? → What could break? → What needs to be tested? That’s where the time goes. Across backend teams I’ve spoken to, the pattern is consistent: → Review is quick → Testing is the bottleneck → Impact isn’t obvious from the diff So engineers end up: → Tracing dependencies manually → Guessing what to test → Over-testing or missing edge cases PR validation becomes guesswork. And when you’re wrong, you don’t know until production tells you. This is broken. I’m working on fixing it: → Map what a PR actually affects across modules and services → Highlight what will likely break → Show exactly what needs to be tested So validation goes from: guessing → clarity Focused on backend systems (FastAPI / Python). If you’re guessing what to test, we should talk.

  • Eliminating guesswork from PR validation
  • → Code is cheap to generate, expensive to validate
  • → Testing takes longer than writing or reviewing
  • → Engineers spend hours figuring out what to test
  • Building a layer that:
  • → Maps PR impact across dependencies
  • → Flags high-risk impact areas
  • → Tells engineers exactly what to test
