Where I'm most useful

• AI product engineering

  LLM features that run in production, not in demos.

  • Led the front end of an AI website builder through its A/B launch, adding voice input and ready-made setups for 2,000+ business types.
  • Found AI-written copy that silently never reached the page and fixed it, lifting placement from 83% to nearly 100%.

• Full-stack web platforms

  Next.js, Express, FastAPI and Laravel, with the auth, APIs and data model done properly.

  • Laravel and Next.js in production, including a web app upgraded from Next.js 13 to 15.
  • AES-256-CBC encryption, Vault, versioned APIs and WebSockets on a green-finance platform.

• Quality, testing and releases

  I write the tests, run the suite and ship the release.

  • Wrote 1,400+ tests across a production web app and its API, and set up its Playwright end-to-end suite.
  • Reviewed 680+ pull requests and ran releases for 5+ repositories.

• Product analytics

  Features ship instrumented, so the decision after launch rests on numbers.

  • PostHog funnels that followed an A/B launch from the first step to a finished site.
  • Build, credit and conversion events in ClickHouse, with failure tracking across every site-build flow and UTM attribution through OAuth signups.
