As the primary escalation point for both internal and external customer issues, I orchestrated pre-launch training and readiness activities for new services, ensuring our team was fully prepared for smooth rollouts. My responsibilities extended to conducting in-depth reviews of operational performance, analysing service disruptions, and strategising on business continuity plans. Collaborating closely with Technical Account Managers and Solutions Architects, I handled high-stakes enterprise customer engagements and escalations, coordinating with subject matter experts to manage critical incidents effectively and reduce resolution times.My commitment to professional development within our team led to significant contributions to the Analytics profile and mentoring of engineers, facilitating their advancement into roles such as Team Leaders and Operations Managers. I managed a diverse group of database and Big Dataengineers, identifying and resolving complex technical issues to enhance service quality across multiple locations. My leadership fostered talent management and professional growth, culminating in the creation of 100 Knowledge Centre videos in 2019, which addressed critical knowledge gaps and supported customer delivery operations.

As a Manager, I have directed multiple projects across the entire project management lifecycle, encompassing solution design, architecture, testing, and implementation, working with teams of varied sizes. I have orchestrated critical database infrastructure and lifecycle management initiatives, such as database consolidation, application sharding, and the integration of reporting loads into read replicas and data warehousing solutions. My management included comprehensive upgrades of over 800 databases, where I standardized upgrade processes and leveraged automation to ensure efficient rollouts.I have supervised both supply chain and customer support tech teams, as well as a diverse team of 10 database administrators in Hyderabad, India, for the AFT and Transportation Organization. Utilizing AWS-managed stacks, I implemented a database automation process that significantlyreduced setup times for Fulfillment Centre launches from two months to one week for on-premises environments, and further down to three days. My strategic focus on system optimizations and collaborative SQL and database tuning led to a 30% year-on-year growth while maintaining operations during three consecutive holiday and prime peaks without impacting fulfilment centers or customer service. Additionally, I have successfully orchestrated Database hardening efforts including SOX and HIPAA compliance for these databases, meeting strict deadlines through effective project management and cross-team collaboration, which included standardizing compliance processes across the organization by creating SOPs based on project outcomes, thus minimizing expenses and enhancing overall operational efficiency.
