Experience
Cloud Migration
Core Financial System
I headed testing functions encompassing 60,000 test cases and a UAT or QA team of 150 bank testers plus 110 Quinnox team members. We ensured timely completion of functional and non-functional reviews, data migration, and front-to-back global ledger reconciliation, interfaces, and reports.
This was a complex integration and amalgamation of disparate vendor technologies with 26 applications covering:
• Finacle and FinnOne as core banking products.
• Veripark Microsoft Dynamics for customer relationship management (CRM).
• Finacle for investment banks and merchant banks.
• SmartVista is a payment solution platform.
• Miles Software for wealth management.
• SAP BusinessObjects business intelligence (BI) platform, Oracle Hyperion Planning, and Oracle Financial Services Analytical Applications (OFSAA) for treasury, reporting, a management information system (MIS), and an operational data store (ODS).
• Pentana for conducting risk assessments in internal audits.
Head of Software Delivery
After the successful progress of the Oracle Financial project, I took on a dynamic portfolio of projects, ranging from core insurance system replacement to creating B2B internet portals, reporting BI portal, and Dynamic CRM. Additionally, I encouraged active business participation within steering groups and Champions of Change to maintain stakeholder commitment.
Finally, I led a timely and quality-centric integration of Microsoft Dynamics CRM, SharePoint, MDM, Oracle E-Business Suite, an enterprise service bus (ESB), and SOA on mondCloud. The annual budget was $32 million.
