About

When production breaks at 2 AM, I own it — the war room, the RCA, the fix, and the playbook to prevent the next one. 16 years keeping mission-critical infrastructure alive across banking, telecom, and enterprise platforms. I sit at the intersection of middleware operations, site reliability engineering, and production support — where system stability directly translates to business continuity. What I own: → 1500+ Oracle WebLogic servers across large-scale distributed banking systems — 99.95%+ availability, 24x7 → End-to-end production reliability: SLI/SLO definition, error budgets, PagerDuty on-call, Sev1/Sev2 response → Middleware stack: WebLogic (10g/11g/12c), OSB, JBoss, Tomcat, Apache, WebSphere, MuleSoft, IIS, Nginx → Automation at scale: 500+ servers managed via Ansible/Puppet/Shell — eliminated manual config, cut go-to-market by 10% → Observability: AppDynamics, Dynatrace, Splunk, NewRelic, CloudWatch, Nagios — SRE Golden Signals applied → Cloud & IaC: AWS (EC2, EKS, RDS, S3, VPC, Auto Scaling), Terraform, CloudFormation, OCI, Azure → CI/CD: Jenkins, Azure DevOps, AWS CodePipeline — 40% faster builds, 30% higher deployment reliability Key wins: → Reduced MTTR by 25% Led critical incident triage and production support across global teams, ensuring rapid resolution of high-severity issues and minimizing downtime (reduced MTTR). → Led Disaster Recovery simulations annually — coordinated failover testing across business and engineering teams → Built SLO-based alerting with PagerDuty, improving incident response time measurably → Delivered Canary and Blue/Green deployment strategies, large-scale parallel deployments and advanced patching across 16+ servers, proactively resolving server inaccessibility and certificate-related failures. → Performed JVM tuning, heap optimization, and connection pool tuning across WebLogic clusters Demonstrated strong ownership and reliability focus by driving end-to-end incident resolution, maintaining system stability, and ensuring seamless production operations. Now layering AI into ops work: Certified across 12+ AI/GenAI programs (Anthropic MCP, Google GenAI Leader, OCI AI, IBM AI Essentials, Databricks Vector DB, RAG with BigQuery). Actively exploring LangChain, LLMs, and vector embeddings to build AI-augmented incident response, log analysis, and runbook automation. Currently pursuing PGDM in Business Analytics (LIBA) — bridging engineering depth with business decision-making. Open to: Senior SRE | Middleware Architect | Production Support Lead | AI-Ops roles

Work experience

Consultant at HCLTech, Jan 2025 - Present · 1 yr 5 mos, Chennai, Tamil Nadu, India, Own SRE operations for enterprise-scale systems — driving production reliability, availability, and incident management across distributed middleware environments. Lead Sev1/Sev2 incident response on-call rotations via PagerDuty — coordinate cross-functional war rooms, root cause analysis, and blameless postmortems. Manage WebLogic and JBoss production environments — applying JVM tuning, heap optimization, and connection pool configuration to sustain performance under peak load. Define and monitor SLI/SLO/error budgets — implement alerting pipelines via Dynatrace and Azure DevOps to detect and resolve reliability risks before SLA breach. Prototype AI-augmented ops tooling using MCP and RAG — exploring LLM-driven incident triage, log summarization, and runbook automation to reduce MTTR. Applied Chaos Engineering principles by simulating failures (server outages, service disruptions) to validate High Availability (HA) and strengthen system resilience. Conducted failover testing and DR drills alongside chaos scenarios, ensuring systems recover seamlessly with minimal downtime. Leveraged insights from controlled failures to improve incident response, reliability, and fault tolerance in production environments. Built and managed infrastructure using Terraform, Ansible, and CloudFormation, enabling scalable and consistent deployments across production environments/creating RDS clusters/creating multitenant Aurora/laravel/PHP

Principal Consultant at ORACLE FINANCIAL SERVICES SOFTWARE LIMITED, Mar 2022 - Dec 2024 · 2 yrs 10 mos, India, Delivered middleware infrastructure for Oracle Banking products — managed WebLogic, OSB, Tomcat, and JBoss environments across multi-tier banking platforms in 3 geographies. Maintained 99.95%+ availability for production banking systems via proactive monitoring (AppDynamics, Splunk, NewRelic) and structured incident management. Implemented ITIL-based Incident, Change, and Release Management — reduced MTTR by 25% through structured postmortems and preventive action tracking. Performed JVM tuning, heap and thread pool optimization, and connection pooling across WebLogic clusters — resolved stability issues and improved throughput under high concurrency. Owned end-to-end vulnerability management — SAST scanning, impact analysis, patch coordination, and zero-downtime production rollouts via Canary and Blue/Green strategies. Authored and maintained runbooks, SOPs, and escalation playbooks — standardized Tier-1 middleware operations and reduced on-boarding ramp time for new engineers.
