Monolithic Legacy Platform Transformation

Legacy to Modern Accounting Engine Modernization


An American corporate investment banking services holding company — and one of the world’s largest asset managers — was burdened with a slowdown in the business due to legacy systems. With their monolithic applications, numerous limitations emerged. As a result, the client:

  • Could not handle interdependencies
  • Faced problems during onboarding, development, and deployment
  • Experienced slow time to market, which made them fall behind their competitors


Due to the monolithic platform, the client was facing many challenges:

  • If the client needed to check for a minor change or issue in the monolithic framework, the entire system had to be tested
  • Given the slow time-to-market issue, there was a risk of customers exploring competitors for alternative options
  • The pressure placed on the interconnected functional components increased the chance of failure


We stepped in to help improve software quality and reduce maintenance costs.

  • Knowing the client’s business could not afford any disruption to its day-to-day operations, we incrementally modernized their legacy accounting engine
  • We constructed the solution with independently testable functional components


For this American investment bank, we incrementally modernized the legacy accounting engine, preventing any possible critical disruption of the customer’s business. This enabled our client to:

  • Experience improved software quality and reduced maintenance costs
  • Increase software portability and enhance security and compliance
  • Ensure a consistent testing environment through behavior-driven development
  • Experience minimal interruptions and reduced risk through incremental modernization
  • Experience reduced hassle in testing new functionalities
  • Accelerate the launch of new features to market
  • Decrease quality assurance costs
  • Reduce development costs
