Problem
CHIP is a product by Avant Garde Technologies B.V., dedicated to giving its customers the very best
products, with a focus on innovation, simplicity, and efficiency. CHIP is a revolutionary instant payment
system that enables peer to peer and peer to business payments securely. CHIP Mobile application has
been developed using Swift for iOS and Java for Android based operating systems. The basic version was written in earlier versions of above technologies and now it is time to upgrade keeping in the view security constraints, technical debt and heavy maintenance on maintaining two different versions of the code base and tech stack.
Solution
During the discovery phase of our review of the documentation, we identified several obstacles to growth and maintaining low costs which are typical challenges faced by startups and mid-sized organizations. To address these challenges, upgrading to React Native technology stack can greatly contribute by reducing maintenance costs through producing hybrid builds for both iOS and Android operating systems, and establishing a solid foundation for adding more app features to ultimately expand the customer base.
Additionally, we found that the backend server followed a monolithic approach where business functions were not separated into microservices. We recommend transitioning to a microservices-based architecture which enables clustering and user load management as the customer base grows. We assisted in creating a production environment with high availability, consisting of multiple production servers and a load balancer for failover management and zero downtime.
