Technology Lead — Release & Application Operations at Infosys Limited (2018-12 – Present)

Managed end-to-end application operations across production and non-production environments for diverse enterprise stack including AEM, Pega, Salesforce, OpenShift, SOA/BPEL, AWS, and NC Suite. Led application decommissioning, change management, incident resolution, disaster recovery planning, and stakeholder coordination.

• Managed end-to-end application operations across production and non-production environments for a diverse enterprise stack including AEM, Pega, Salesforce, OpenShift, SOA/BPEL, AWS, and NC Suite — ensuring high availability and operational stability.
• Spearheaded decommissioning of 15+ legacy applications, managing the full application retirement lifecycle including infrastructure reclamation, stakeholder sign-off, and documentation — reducing operational overhead and compliance risk.
• Planned and managed application environment refreshes, dry runs, and deployment readiness validations, ensuring environments were compliant and stable ahead of each release cycle.
• Monitored application and infrastructure health using DynaTrace and OBM, enabling proactive incident detection and rapid response to performance degradations.
• Managed artifact repositories (Nexus, Harbor, Git/Bitbucket) to maintain build integrity, version control, and audit traceability across multiple environments.
• Coordinated with the Change Advisory Board (CAB) to analyse change risks, assess impact, and schedule patching activities across all environment tiers — ensuring compliance with IT change governance policies.
• Facilitated end-to-end incident resolution by analysing failure impacts, identifying root causes (RCA), and providing actionable recovery guidance to cross-functional technical teams using JIRA and BMC RemedyForce.
• Authored comprehensive SOPs and troubleshooting runbooks to standardise known failure resolution, enabling faster identification and recovery of recurring incidents across teams.
• Coordinated with infrastructure, development, and operations teams to implement permanent fixes for recurring issues — reducing repeat incidents and improving overall application stability.
• Orchestrated complex change requests in alignment with master release cycles, providing deployment support to achieve minimal downtime and maintain environment availability.
• Planned and executed DR dry runs and environment refresh activities to validate application recoverability and ensure alignment with business continuity requirements.
• Maintained deployment runbooks and technical installation notes as living documentation to support DR execution, operational handover, and service continuity across teams.
• Orchestrated cross-functional coordination across Infrastructure, Operations, QA, and Development teams to ensure seamless service transitions and release readiness.
• Aligned multiple internal and external stakeholders on operational readiness, cutover plans, and post-deployment validations — improving communication efficiency and reducing unplanned incidents.
• Acted as technical evaluator in the hiring process and managed onboarding lifecycle, authoring training materials and providing hands-on mentorship to ensure adherence to operational SOPs.
• Developed a Bash and Python-based automation framework within Jenkins for CQA Baselining, reducing manual effort by 40% by implementing automated workarounds for known recurring environment failures.
• Managed CI/CD pipelines using Jenkins, GitLab, Ansible (AWX/Tower), TeamCity, and UC4 — streamlining deployment lifecycle and reducing manual intervention across the enterprise stack.
