A large national mortgage lender that originates and services home mortgage loans through 280 branch offices and over 14,000 affiliates across the United States.

Client's primary goal was to significantly increase the amount of mortgage loans issued by streamlining and accelerating the loan origination process. The Company initiated the implementation of a new loan origination system based on cutting edge Service Oriented Architecture (SOA) technologies.

Because of the mission critical nature of the system, the client required a 24-hour global testing cycle and also desired in-house competency to mitigate risks of system instability and production outages.

The full spectrum of Aaxis' System Optimization Services (SOS) was engaged, from inception phase onward, to ensure the delivery and deployment of a stable, scalable and fault-tolerant end product. Aaxis went through the following steps:
