How I work

I build AI systems and I test them. Doing both means reliability is designed in, not bolted on.

  1. Build

    Design the AI system or automation around real data and real failure modes: where state lives, what gets retried, and where failed payloads go.

  2. Integrate

    Connect models, APIs, databases, and business tools, with structured outputs so downstream steps can trust what they receive.

  3. Test

    Test it the way I test client platforms: end-to-end journeys, edge cases, malformed inputs, and forced upstream failures.

  4. Verify

    Check the stored data and the API behavior, not only the screen, and verify fixes with regression checks.

  5. Deploy

    Ship to production with documentation and a Loom walkthrough, so your team knows how it works and what to do when something breaks.
