Digital Shared Services Platform | September 2023 - Present 

Client - Barclays

Digital Shared Services(DSS) platform acts as a Secure Proxy/wrapper for MCA EPS Layer, a thin layer between invoking channels (ROLB, BMB, AS3, FORMS) & the MCAs. The main purpose of DSS is to expose MCAs to channel features/applications in an efficient way. This means DSS can take care of overhead activities to invoke MCAs and hence the corresponding features can solely concentrate on business/functionality logic rather than worrying about how to invoke MCAs. It is also built on decoupled architecture which ideally means each feature will have their own dedicated aPaaS infrastructure, this empowers individual feature teams to plan for quick GO-LIVE rather than depending upon other DSS features.
