About me

A bit of context

I build mobile and web products, from Flutter apps to Next.js portals. At MeldCX / Skunkworks I work across the client, APIs, and data, including on-device vision and member platforms.

Before that I was the sole mobile developer at YAHSHUA Outsourcing Worldwide. I led the move from native Android and iOS to Flutter and shipped the ABBA workforce apps through the App Store, Play Store, and AppGallery.

Skills

What I bring to a team

  • Flutter & Dart
  • Next.js & TypeScript
