From 120 Days to 10: Redesigning Customer Onboarding Through End-to-End Banking Process Automation

There are challenges with banking existing customer onboarding and it is manual, decentralized and lengthy. Onboarding could take more than 120 days because of siloed applications, duplicate data entry, regulatory checks , etc. This paper proposes a sheltered and an automated customer onboarding with an end to end onboarding solution. We optimize the onboarding time to 10 days with integration of multiple latest technologies such as microservices architecture , micro frontend architecture , kafka messaging, cloud native, devops practices. We show case our solution for UI domain, we used Angular and React technologies. For application domain we used Java with Spring Boot Controls. For data repository, we used Mongo DB. For asynchronous messaging, we used Kafka. Solution has KYC aggregation for the company, robotic process automation (RPA), cloud infrastructure (AWS) and integrates for onboarding with TSYS. Results from the solution exhibited improved processing efficiency, data accuracy and compliance aligned onboarding. Work is scalable and replicable across financial services institutions.
