ABOUT PURNIMA AGGARWAL
Production Support Analyst with hands-on experience supporting business-critical banking systems in live, high-availability environments. I specialise in incident management, real-time troubleshooting, and service recovery, ensuring system stability and minimal business impact across 24/7 operations.I work extensively with mainframe technologies including COBOL, JCL, REXX, SQL, cloud, splunk, and IBM z/Series and i/Series platforms, supporting batch and online processes, resolving job failures, and analysing system and application issues at source. I am experienced in managing live incidents, performing root cause analysis, and collaborating with development and infrastructure teams to deliver effective, long-term fixes.Alongside traditional mainframe support, I have exposure to API and cloud-integrated environments, enabling seamless support across hybrid systems. Known for strong problem-solving skills and calm decision-making under pressure, I take a structured and proactive approach to incident resolution, continuous improvement, and operational resilience.
