NewProduction Readiness Audit for AI-built apps

Software ready for real users, shipped fast at a fixed price.

I'm a senior engineer with 20 years of experience shipping software. Modern AI tooling lets me build faster and charge less, and you get a fixed quote before any work starts.

How I work

Four steps, with the price settled before any work begins.

  1. Tell me what you need

    Tell me about the project and what done looks like.

  2. Fixed quote

    I send a written scope and a fixed price. That price holds unless you change the scope.

  3. Build

    I build in short steps and show you working versions as I go, so surprises show up early.

  4. Handoff or ongoing support

    I hand over the code and documentation. If you want help after launch, ongoing support covers maintenance and new features.

If you start with a Production Readiness Audit, the audit fee is credited toward any build above.
