Assisted in the development and implementation of the Vault Management System (VMS) for the Bank of Ghana. Studied business and technical specification documents for system understanding and customization. Developed T24 reports and subroutine programs using jBase programming language.

Assisted in the development and implementation of the Vault Management System (VMS) that keeps track of currencies at the Bank of Ghana (Impact 05 Project R5 Implementation). Also assisted in the Bank PHB R8 Implementation. Responsibilities included: • Studied the VMS business and technical specification document as well as same for the automated teller machine (ATM) for Bank PHB. • Tested, troubleshooted and customized some T24 version screen for full proof of their functionalities. • Designed T24 reports and wrote subroutine programs for input validations and authorization using jBase programming language. Other reports ranged from asset register, loans and deposits, T-Bills, tellers, letters of credit, documentary credits and deal slip etc. • Monitored Close of Business (COB) and captured screenshots of errors. • Assisted in end user training.

Assisted in the implementation of the Inventory Control System. Engaged in stock taking, pallet labeling, and other office duties.
