About

Hi, I'm Dy,

Self-taught developer and designer, based in Nantes, France, and building for Android since 2016. In 2018 I released Inware, an app that shows you exactly what your device is made of. It was the first app on the Play Store to support Material You dynamic color, before the feature was even documented, and has since passed 500,000 downloads while holding a 4.7 rating.

Since 2016, I've been spotting Android features before they're announced: Fast Share, which you now know as Quick Share, and the rename of Bard to Gemini, days before it was official. That's how I ended up contributing to 9to5Google, where I also wrote a few pieces of my own.

In 2024 I joined Texts to work on its Electron desktop app, then moved to Beeper's Android app. I later took on design work there too. Among other things, I reworked the app's navigation and overhauled its color system around Material 3.

I sometimes dig into other people's software too. Back in 2022, I reported a flaw in Huawei's AppGallery that let anyone download paid apps for free. A year later I looked into Nothing Chats, which was built on a service called Sunbird, and what I found got the app shut down.
