( Who builds the apps )

I build apps with React Native and Expo. Ideally from the first line of code all the way to the store.

I've been a mobile and frontend developer for over four years, and before that I spent three years training as an IT specialist. Most recently I helped build an app that around 130,000 people use every month. I work best when I'm close to design, product and backend. Remote works just as well for me.

And in the evenings I sit down with my own apps. You'll find all of them here.

Career

  1. 2019–2022

    Apprenticeship at T-Systems Multimedia Solutions

    IT specialist for application development, finished with a 1.9 (on the German scale, 1 is the best). During that time I tried out a lot with VR and the Nreal AR glasses and built prototypes, for example a virtual apartment viewing. My final project was an SDK for building VR prototypes like that.

  2. 2022

    My first own app: Pure Weight

    My first own app: a fitness tracker built with Expo, for workouts, progress and charts. For the Pro version I added in-app purchases with RevenueCat, and I got the app into the Apple App Store myself.

  3. 2022–2024

    Web developer at Check24

    Here I worked with React and TypeScript in a big team. I built new features together with product, QA and backend. On the side I looked after the component library the whole company uses and took a big monolith apart into smaller projects.

  4. 2024–2026

    MetaFlow from scratch, at Ambient Digital

    Here I built MetaFlow with Expo from scratch, with the Shopify login, the onboarding and the gamification. The data comes in through TanStack Query, the state lives in MobX and Jotai, and the app speaks several languages. Builds and releases run through GitLab CI and EAS.

  5. Since 2026

    App developer at MetaFlow

    Now I am right in the MetaFlow product team. The app runs on iOS and Android and has around 130,000 users a month. I build features from planning to release, build a design system together with design, and make sure the app keeps up with new versions of iOS, Android and Expo.

Tools

Mobile
React Native, Expo with EAS Build, Submit and Update, Expo Router, Reanimated, Skia, releases for iOS and Android
Frontend
TypeScript, React, HTML, SCSS, design systems
Data and state
TanStack Query, MobX, Jotai, REST-APIs, Shopify-APIs, RevenueCat
Backend
Supabase with Postgres and Realtime, Node.js, Express, Socket.io, Python basics
In the team
Git, GitLab CI, Jira, Notion, Figma, Claude Code
Away from the code
Strength training, running, gravel biking and hiking. So it's no coincidence that two of my apps are about training.
