A solo developer documented 112 straight days of building and shipping an app toward a $1M goal and distilled 10 lessons from the process. The focus is sustaining daily progress, keeping scope small, and deciding what to ship next to maintain momentum.

[ WHY_IT_MATTERS ]
01.

It sets a realistic benchmark for how fast small teams can iterate with disciplined workflows.

02.

The habits and feedback loops translate directly to backend and data teams aiming for shorter cycle times.

[ WHAT_TO_TEST ]
  • terminal

    Pilot AI assistants on boilerplate backend tasks (API scaffolding, schema migrations, ETL skeletons) and measure time-to-PR and defect rates.

  • terminal

    Add automated evals (unit/property tests, type/SQL checks) to score AI-generated changes and track hallucinations and latency.

[ BROWNFIELD_PERSPECTIVE ]

Legacy codebase integration strategies...

  • 01.

    Start with AI-assisted PR comments and test generation on a single service to avoid risky auto-commits.

  • 02.

    Gate AI changes with codeowners and CI quality bars to control dependency churn and build times in monorepos.

[ GREENFIELD_PERSPECTIVE ]

Fresh architecture paradigms...

  • 01.

    Set up an AI-first repo structure (clear modules, templates, prompt examples) and enforce IaC for fast, repeatable envs.

  • 02.

    Use ephemeral preview environments so AI-suggested changes can be built, tested, and benchmarked safely by default.
