What we did

Business Impact

Apiumhub worked with Bitpanda since July 2021 until March 2023. Bitpanda recognized Apiumhub as one premium partner to lean on for critical tasks.

Apiumhub’s goal was to refactor the whole accounting and user management system, as Bitpanda had grown a lot in user base, the platform could not sustain the traffic under load.
Apiumhub worked along internal Bitpanda teams to provide a new architecture, microservices and went to low level to optimize security protocols to make the platform support more load.

In parallel, we also refactored the whole Login/Registration microservice in Web frontend (Angular), Android and iOS, implementing past missing features such as AB Testing, feature flags and user behavior analysis tools.
