Experience
Infrastructure Engineering Management
My role involved managing Windows Server support within Agile and Scrum@Scale, significantly improving team productivity and project delivery times. I instituted the "infrastructure tribe leader" role, eliminating unexpected impacts on infrastructure changes and ensuring seamless operations. I also facilitated cross-team technical and administrative incident management, leading to faster resolution times and improved client satisfaction.
Additionally, I achieved 100% completion and approval of team SOWs and SOPs within expected timeframes during a critical transition from a per-head to a service model. I crafted detailed SOWs for all managed groups, defining roles and client expectations and increasing clarity and performance. I also created SOPs for three teams, establishing consistent operational procedures and enhancing overall efficiency.
Microsoft Exchange Mailbox Migration
In addition to this tenant-to-tenant migration, I spearheaded the migration of 120,000+ mailboxes from our on-premises Exchange system to Exchange Online within six months. This endeavor required migrating mailboxes with substantial data volumes, with some exceeding 100 gigabytes of active storage and 50 gigabytes of archived information per mailbox.
Throughout these migrations, I maintained daily operations of Exchange servers, overseeing incident and problem management for the messaging team. My role included addressing and resolving technical issues, optimizing performance, and ensuring robust security protocols were in place. My leadership and expertise were instrumental in achieving a smooth transition and upholding the highest service delivery standards.
