The core financial systems of BEST were created in the nineties and then regularly extended with more complex functionalities. Eventually, the obsolete solutions stopped the further growth of BEST. Jit Team helped BEST to develop brand new custom solution which would replace the legacy software used at the time.

Jit was responsible for the technical architecture of the core system. In addition Jit shared knowledge and experience on building complex IT systems from the ground up including best practices on automation and development pipeline supporting continuous integration & delivery.

The technical architecture was event-driven and was implemented using asynchronous messaging following modern trends in IT. The resulting system is scalable and highly modular allowing for continuous improvements and extensions done by multiple development teams working along each other.

Success of the project lied in the effective and direct cooperation with both the IT and business teams of BEST.
