7+ years building mobile apps used by millions.

I own the mobile side end to end: the architecture, how data moves through the app and in and out of the API, the code itself, and the CI/CD that gets it to the store. Hands-on with Flutter and Android, currently technical team lead on the flagship project at Greentech Apps Foundation.

Experience

Sr. Software Engineer, Mobile — Greentech Apps Foundation

Technical team lead on the flagship project — a Flutter and Android product with millions of installs. I set the architecture and data flow, review what goes into the codebase, and keep the release pipeline moving.

• Set the app architecture and data flow, and agree the API contract with the backend team before work starts.
• Own the CI/CD pipeline and the Play Store and App Store releases that come out of it.
• Plan new projects with product managers, testers and developers in an agile scrum environment, from design through release.
• Design and build advanced applications across Android and iOS.
• Modernise legacy applications — fixing bottlenecks, improving performance and adopting current platform features.
• Own performance, quality and responsiveness on both mobile platforms.
