Technical solution

When developing a web tool for publishers, it was necessary to create a database with reliable information on the German energy sector. Retrieved via the API, we aggregated the industry data from a government resource and enabled the client company's publishers to work with it. Additionally, we developed a web builder to generate charts and comparison tables based on this data to easily integrate them into publications both on the client's and third-party resources.

We used the React Native framework to develop a mobile app, and the cross-platform approach made it possible to cut the development costs by 40% and get applications for both iOS and Android platforms.

Our solution provides the ability to save previously opened articles to a local storage and read them without the network access. We designed and implemented an authorization system to separate the accessible content for two groups of users. To view the magazine in PDF format, we integrated a convenient viewer into the mobile application using the rn-pdf-reader-js library. We also deployed the application to the App Store and prepared all the accompanying documentation.
