A technology start-up wanted to develop a scalable dating application (Android) with gamification features enabling users to find their perfect match and monetize it through in-app purchases.
Technologies & tools
Server- and web-based components: PostgreSQL (including Poistgres-XC and Pgpool-clustering for read/write scalability), Amazon RDS Cloud;
Mobile app: Android SDK, Retrofit, RxJava, Dagger, OkHttp, Socket.IO, Google API, Twitter API, Facebook API;
Project team
2 Android developers, 1 Team Lead, 2 PHP developers, 1 Tech Lead, 1 Project Architect, 1 PM, 1 QA.


Our customer listed scalability as one of the major requirements for the app. Taking into account the anticipated workload and amount of users, the we suggested using the PostgreSQL database and Amazon RDS for the backend part. We also developed a Web-based administration panel using our own PHP framework and implemented the SSL protocol to secure communication between the app and the server. A custom matching algorithm was the most challenging component of the Android dev project. The Dating App users provide short answers (yes, no, maybe) to a range of psychology questions; the algorithm analyzes user feedback and matches the results to those of potential partners. The app also supports live chat between users who “liked” each other and can be paired with a user’s social media accounts.

Key features of the dating app include:

  • Simple registration and secure authorization;
  • User and profile management;
  • The questionnaire and live chat;
  • In-app purchases unlocking specific matching categories.
