SystemAdministrator, Cisco May 2025 – Present New York

• Maintained enterprise IT infrastructure supporting manufacturing and operational systems, ensuring 99.9% uptime across mission-critical applications, backend services, and distributed production workloads used in regulated enterprise environments.

• Supported new product introduction (NPI) by validating infrastructure readiness, system configurations, network dependencies, and deployment environments, enabling 100% successful transition from staging to pilot production releases across integrated systems.

• Reduced recurring system incidents by 22% through structured ITIL-based incident management, RCA workflows, and proactive monitoring across enterprise observability platforms and alerting systems.

• Administered enterprise infrastructure systems including Linux/Windows servers, authentication services, and network-adjacent components, ensuring stable performance, patch compliance, and minimal production downtime.

• Collaborated with engineering and operations teams on change management, release coordination, and rollback planning, reducing deployment failures by 18% during production rollout cycles.

• Strengthened system security posture by enforcing IAM policies, access control frameworks, patch management cycles, and system hardening standards aligned with enterprise compliance requirements.

• Improved system observability by analyzing logs, performance metrics, and infrastructure telemetry using monitoring tools, increasing incident detection efficiency by 30% and reducing resolution time SystemAdministrator, Crest Data Sep 2020 – Sep 2024 India

• Managed multi-cloud production infrastructure (AWS, Azure, GCP) supporting 175+ enterprise customers, maintaining 99.9%+ system availability acrossdistributed hybrid environmentsand microservices-based architectures.

• Designed and maintained enterprise observability stack using Splunk, Datadog, and Dynatrace, reducing incident detection time by 40% and MTTR by 35% across large-scale distributed applications.

• Automated Linux server provisioning, patch management, and infrastructure configuration processes using Python scripting and system administration tools, reducing manual administrative effort by 45% and improving operational consistency across production environments.

• Strengthened cloud security posture through IAM governance, least-privilege access control, identity management policies, and system hardening, reducing security incidents by 55% across production infrastructure.

• Managed high-severity production incidents via ServiceNow ITIL workflows, incident escalation processes, and SLA tracking, achieving 95%+ compliance and reducing P1 resolution time to under 30 minutes.

• Leveraged Jira and Confluence for incident tracking, change management documentation, and cross-functional collaboration, improving operational transparency, knowledge sharing, and issue resolution efficiency across infrastructure and support teams.

• Supported large-scale cloud migration projects, enabling 60% faster workload migration and improved scalability of legacy systems into cloud-native architecture withminimaldowntime.

• Implemented AIOps-driven monitoring and alert correlation systems, reducing false-positive alerts by 40% and improving proactive incident response accuracyacross enterprise environments.
