At OrangeTech, I delivered an in-house leave management system built as a modular Next.js application, with a focus on testability and fast delivery. I also implemented Cybersource card-on-file charging with 3-D Secure, processing approximately 100 test transactions per day in controlled live testing.
I developed backend microservices and REST APIs for NayaOne’s secure sandbox at turntabl, and delivered Java and Spring Boot rules-engine features for Morgan Stanley institutional trading systems. Earlier, at Dizengoff Ghana, I reconciled bank balances and accounts in Epicor and resolved posting errors and auditor queries.
