I ensured the reliability and performance of EOP ITAR cloud-based infrastructure and related systems. I collaborated with Microsoft EOP infrastructure and deployment teams to reproduce and eliminate pipeline workflow failures on ITAR Stateful/Stateless/Sonar servers. In addition, I oversaw and assisted with software development, conducted regular maintenance, performed performance tuning, and responded to escalated site reliability issues. I also participated in on-call rotations to address server reliability concerns.

• My major focus was on maintaining ITAR Azure GovCloud environments, where I ensure strict adherence to compliance and regulatory standards throughout the entire lifecycle.
• Deployed, automated, maintained, and managed Azure GovCloud-based production systems, guaranteeing high availability, optimal performance, scalability, and security.
• Automated CI/CD pipelines for code deployment across a vast network of over 15,000 cloud servers using PowerShell.
• I actively managed, improved, and monitored the cloud infrastructure for Exchange Online Protection (EOP) – ITAR Servers. This encompassed tasks such as deploying updates, applying patches, and managing backups.
• Achieved a 20% reduction in cloud infrastructure costs by implementing cost optimization strategies. This not only reduced unnecessary server deployment incidents by 50% but also significantly accelerated our production processes.
• Improved site reliability by 25% through the development and implementation of automated monitoring and alerting systems. Additionally, I authored infrastructure manifests and modules to efficiently deploy, configure, and manage servers.
• Discovered vulnerabilities in Microsoft SQL Server network security by resolving permission issues on their HPE Integrated Lights-Out servers.
• Employed a three-phase ETL process to extract, transform, and load data into an Azure container. This data was then utilized for project planning and collaborative code development.
• Worked with Azure Monitoring tools such as Azure Log Analytics, Azure Network Watcher to diagnose and minimize service degradation.
