Enterprise Application Management & Operational Risk Support

Supporting Mission-Critical Banking Systems in a Regulated Environment

Assistant Vice President, Specialist IT – Application Manager


As an Application Manager at BayernLB, Michelle supports mission-critical enterprise banking applications across trading, finance, regulatory reporting, and compliance environments. Operating within a highly regulated setting, she focuses on application stability, secure change management, testing, and audit readiness while partnering with internal teams and platform service partners to ensure operational resilience.


Application & Service Management
Michelle manages and supports 10+ enterprise applications used by approximately 100 employees, coordinating incident and service request resolution to ensure SLA compliance and minimize business impact. She implements application fixes and enhancements based on documented user stories, following structured SDLC and change management practices using JIRA and Azure DevOps.


Testing, Validation & SAP Readiness
To support SAP transition efforts, Michelle developed a centralized Microsoft Access database used for testing, validation, and reporting. The solution enables Accounting teams to import, compare, and reconcile financial data across SAP financial tables, regulatory reporting, general ledger, and account movement sources—supporting parallel testing and reducing operational risk during system transitions.


Operations, Controls & Risk Awareness
Michelle manages end-of-day processing and operational exceptions, coordinating closely with Accounting to resolve data import issues and ensure daily processing integrity. She monitors security alerts and reviews logs to support continuous monitoring, maintains control documentation for audits and regulatory reviews, and participates in enterprise system upgrades and resiliency testing to support business continuity.
