Hyderabad, India | Technical leader for enterprise multi-service infrastructure management, platform reliability, and cloud operations powering ServiceNow's Global 2000 multi-tenant cloud (99.99%+ uptime).

  • Multi-Service Fleet Operations: Managed foundational cloud and Linux infrastructure supporting dozens of interconnected enterprise platform services, API gateways, and distributed data pipelines; maintained strict 99.99%+ uptime across thousands of compute nodes.
  • Relational Database Operations (MySQL & PostgreSQL): Supported enterprise relational database tiers powered by MySQL and PostgreSQL, managing automated backup pipelines, primary-replica replication health, connection pooling (PgBouncer, ProxySQL), and failover validation across distributed platform services.
  • Middleware & Software Load Balancing: Configured and tuned high-throughput software load balancers (HAProxy, Nginx) fronting multi-service Apache and Tomcat application tiers; optimized connection pools, keep-alive timeouts, buffer limits, and health checks to ensure seamless request distribution and zero-downtime rolling service deployments.
  • Resource Isolation & Capacity Governance: Enforced strict compute, memory, and I/O isolation across co-located multi-service workloads utilizing Linux cgroups and systemd resource slices, eliminating noisy-neighbor degradation and optimizing multi-tenant cluster density.
