5ife is a neo-banking platform that offers various financial services and crypto integration and other (AI) features to its customers.
It was a greenfield project where the whole application and infrastructure was built from ground up.
One of the biggest challenges of the project was that we needed to cope with a lot of sensitive data and the expected user load was immense. The application was supposed to be designed in a way, so that it can handle thousands of transactions per second, without losing any data and the highest security standards needed to be ensured. Another lethal factor was the performance, when you want to cope with competitors on the market, the app needs to be as performant and reliable as possible.
The application was built in a hybrid manner, with React Native and the backend was based in the cloud (AWS). An event based microservice layer was built with Kotlin and Spring and to ensure performance and to prevent data loss we implemented Kafka.
Main Tasks:
