Notes from building the thing.

Writing on AI product development, engineering and the specific ways projects fail between a working prototype and a working product.

In progress

Being written.

Outlined and queued. Listed here rather than published as empty pages — these aren't live yet.

  • AI EngineeringDraft

    The smallest useful AI evaluation harness

    You don't need an evals platform to know if a prompt change helped. A fixed test set, a scoring function, and a number — the minimum that actually works.

  • App RescueDraft

    Why your first App Store submission keeps getting rejected

    The rejection reasons that catch first-time submitters every time, and the checklist that would have caught them before Apple did.

  • App RescueDraft

    You inherited a codebase and the developer is gone

    No documentation, no handover, no one to ask. A method for making an unfamiliar codebase safe to change before you touch a single line.

  • AI Product DevelopmentDraft

    What an AI MVP actually costs to run

    Model calls are the line item nobody models until the first invoice. A framework for estimating per-user cost before you launch, not after.

  • AI StrategyDraft

    Build AI in-house, hire a studio, or buy the tool

    Three real options, three different failure modes. A way to reason about which one fits your team's actual constraints, not its ambitions.

Beyond reading

The writing is general. The engagement isn't.
