Design + Code in one 💻 🎨 🏳️‍🌈
Building brandtnew apps with React Native, Expo, and Supabase. Built & sold WeBurn 💪 Now working on @roamwise.app
I'm in love with @expo.dev, @swmansio.com's Reanimated, and gorhom's Bottom Sheet ❤️

Normally I’m all for keeping things simple — no unnecessary UI or animations.

But I’m a big fan of the Joi app and just had to recreate how the buttons animate when the bottom sheet changes position.

Fun fact: @roamwise.app’s design is heavily inspired by Joi and Flighty ✨

Spent one weekend building a custom animation system on top of @swmansion.com’s Reanimated and @expo.dev router.

Every animation in my apps now feels on-brand — and I can animate anything in seconds.

Recording your work to share it? Great way to catch bugs 🐛

Just spotted some unnecessary re-renders in the Roamwise calendar while filming a demo 😅 #reactnative #expo #indiedev

I’ve shared this animation before — but now it’s finally dialed in.

✨ Snappy pop-in scale on the buttons
⚡️ Fast spring for the progress bar
🌈 Interpolated colors on the progress dots

Built using @expo.dev & @swmansion.com’s Reanimated.

Schengen rules are confusing. Roamwise isn’t ✨

I just launched SchengenPro — a new feature that gives travellers a clear, visual overview of their 180-day Schengen timeline.

Here’s what it does and why I built it 🧵 #indiedev #reactnative #expo

5/ Admittedly, I spent way too much time perfecting the user experience. I even built my own animation system based on Reanimated—which I'll be using for future apps, too (right? 😅)
