Learn about new Internship opportunities for 2020


In HoReCa business managers struggle to manage the team during the periods of mixed demand with temporary peaks like sponsored parties or weddings. Often the need several people for temporary assignments. What they are looking for is a crew of experienced workers, with proven track record and recommendations from fellow restaurants/hotels so that they can make a quick scale with a quality workforce.

The main challenge behind the GastroJob project was to reflect the specific business processes like recruitment within the mobile app interface.

For our client, we've created multiple interfaces, with mobile apps for the employees as well as employers. You can see the complete case study which takes into account the key takeaways from building the ecosystem of Flutter application on our presentation from Flutter Europe:

What was interesting about this project was the fact that at some stage we have established with the client that in order to extend the features available in the application it would be advisable to transfer from Xamarin to Flutter. As a result we had a unique opportunity to compare the results from two projects where the exact same scope has been developed on Xamarin and Flutter. Even further, we've could compare the time spend on development of the Flutter Employer app against the time spent on the web portal for the employer with exactly the same feature scope. It was proven that with Flutter we were able to recreate the scope substantially quicker, spending less than 70% of the time needed to build the mobile app with Xamarin or the Web app with React JS. Here are the detailed results:

In summary, we were working with the client for more than 2 years, adding new features and components as a response to the market needs and pivots experienced by the Startup. So far the app has enabled several thousand users to find the great jobs they were looking for in the HoReCa industry.
