Available for new projects
I build React Native apps people forget aren’t native.
Mobile developer working across iOS and Android from one codebase - fast lists, smooth gestures, offline-friendly data, and the release work that gets an app through review and into people’s hands. When a project needs a website to go with it, I build that too.

About me
Hi, I’m Joy. I build iOS and Android apps with React Native and Swift - the kind people open every day for learning, work, food and money.
I also build websites with React, Next.js, PHP, Python, HTML and CSS, usually when an app needs a home on the web. And from time to time I dig into data analysis, mostly to keep learning and to understand the products I work on a little better.
Off the clock, I’m usually trying to keep up with Max, my four-year-old German Shepherd, who does zoomies and chases balls only he can see. Otherwise I’m replaying the Tomb Raider trilogy or Little Nightmares, with the Beatles or the Eraserheads on repeat.
