Site Reliability Engineer at Landmark Groups building AI-powered SRE agents that cut manual effort by 20%.

India

Message

At Landmark Groups, I lead 24x7 SRE operations and mentor an 8-member L1 SRE team. I developed AI-powered automation with Go and Python that reduced manual effort by 20% and improved MTTR.

I built the Landmark SRE Operations Dashboard and integrated agent-based automation with Grafana, Loki, New Relic, and Kafka Conduktor to support proactive detection and remediation.

At Walmart, I supported Sam’s Club applications including Quick-Pick, GIF, and Membership Express. I developed monitoring dashboards and alerting workflows, and contributed to a Splunk-to-OpenObserve migration.

At Infosys, I worked on application maintenance and development for Goldman Sachs and built Spring Boot microservices. A software change I deployed reduced system errors by 30%, while Prometheus and Grafana supported observability and incident detection.
