Flutter apps built to survive production.

Mobile software engineer since 2018. I led native-to-Flutter migrations for banking and security products, and I keep flagship hospitality and theme park apps fast once millions of people are actually using them.

About

I hold a Bachelor’s degree in Computer Science and have spent my career building cross-platform mobile applications. Flutter is my primary framework — I use it to ship apps that stay fast, readable and maintainable as teams and codebases grow.

Most of my work has been on flagship products already in production: a banking app with over a million downloads, a rewards app for one of the largest hospitality groups in the world, the flagship app of a global theme park operator, and a security monitoring platform sold to enterprise customers. That means the interesting problems are rarely greenfield — they are memory leaks under real load, native bridges that have to not break, and migrations that cannot drop a feature.

I also work comfortably in native Android and iOS, which is usually what makes a Flutter migration survive contact with the existing codebase.
