Global Rank Softwareentwicklung UG chose Bamboo Agile to deliver a mobile rankings app that required integration with multiple external API’s, including Steam, Google Places, and OpenStreetMap, and also real-time user tracking plus location search and storage over the entire OSM database.


Developing a special algorithm allowing to store the geodata and calculate rankings at any given time.
Implementing multiple optimizations and custom bypasses to the backend part of the project (due to the algorithm being demanding to processing power).

Technologies we used:

Node.js, MySQL, ElasticSearch, Redis, Android
