Immoweb is the Belgian real estate platform. Their app is one of the most downloaded app in the country.
Besides developing new features in Swift, I also increased the test coverage by 15% while reducing the crash rates to less than 0.4%.
I also put a lot of work on improving the continuous integration environment (Jenkins) and created many different automated UI tests. Later on, I worked on creating a shared code base for the iPad version of Immoweb.
All these led to better rankings on the App Store and a more stable app.
