Monolithic to Microservices

Client Background

  • This client is a leading provider of mortgage origination solutions, working with thousands of lenders turning over 50,000 loan applications per month
  • The company’s legacy loan origination application was desktop-based with client-server architecture
  • Loan information was delivered to applicants no sooner than the next day, which delayed the overall process, causing poor customer satisfaction and eventually revenue loss
  • Other challenges included difficulty in maintenance and limited scalability of the application and an interface that was not very user-friendly
