At Wipro, I support Citi production systems, patching and maintaining Linux servers running WebSphere and Tomcat. I completed the VTM patching cycle ahead of schedule with zero rollback and maintained approximately 99.8% SLA compliance.
For Citi, I respond to WebSphere and Tomcat production issues and monitor system health using Grafana and ServiceNow. I also manage SSL certificate renewals, DNS records, and Windows Server certificate updates.
For Electronic Arts, I managed the Change Management lifecycle and helped raise team KPI performance from about 10 percent to about 90 percent. I also developed a site- and time-zone-based change-notification process with application engineering, reducing user queries and ticket volume during planned change windows.
