I build products from the data model up: backend APIs, application logic, authentication, permissions, background jobs, and the web or mobile interface that uses them. I work in Flutter and Dart when mobile is the right surface, and in TypeScript and Next.js when the product lives on the web.

The goal is a product that can be used, deployed, and extended. Architecture earns its complexity; everything else gets the smallest reliable implementation.

What this can include

  • SaaS and web applications
  • Flutter applications for iOS and Android
  • MVPs and new product builds
  • Product features and user flows
  • Authentication, permissions, and data
  • Deployment and production handover

Example engagements

  • Build an MVP from requirements to a working release
  • Add a substantial feature to an existing product
  • Take a prototype to a deployable production build
  • Build a cross-platform Flutter client for an existing API

Examples describe the shape of the work, not past client engagements.
