Decoding Legacy Systems Under Tight Deadlines
The project had a predetermined timeline of three months, with the aim of developing a Proof Of Concept (POC) for replacing the bank's mainframe with a modern microservices architecture. The mainframe apps we aimed to replace were developed over several years and it was a challenge to study the system with limited technical documentation available. Despite these restrictions, the developers at Edstem were able to deliver a full solution architecture and a working POC with all the agreed components on time.
