When cleanup is worth it
Cleanup is worth doing when the product has traction, the same bugs keep returning, new AI-generated changes break older features, or you want another engineer to work on the app without starting from scratch.
What we clean up
- Repeated components, duplicate business rules, and tangled state.
- Unclear data models, unsafe database access, and missing validation.
- Configuration spread across code, dashboards, and generated comments.
- AI prompts and tool calls without boundaries, limits, or test cases.
- Critical flows without tests, logs, or rollback notes.
What we avoid
We avoid cosmetic rewrites that make the code look different without reducing business risk. The best cleanup preserves working behavior while making the app safer to change.
Outcome
You get a codebase with clearer structure, documented assumptions, safer configuration, and a realistic path for future feature work. The founder should leave with more confidence, not a pile of abstract engineering recommendations.
