Experience
Mobile & Full-Stack Engineer
Propstack GmbH
At Propstack I was hired to lead the mobile app development after a longer period of stagnation. Parts of my plans to update the codebase and prepare the app for future development were:
- refactoring of the app, reimplementing stores, models, API client, screens and components using Typescript
- adding performant on-device storage for stores as a preparation for an offline mode
- adding the RNUILib to achieve a minimal and modern UI design fast
- implementing native packages to provide more features (e.g. displaying of Caller Ids)
After the initial refactoring and redesign of the app, I will start working on feature development and improvements to the UX.
