About Abhishek S.

Senior DevOps and Site Reliability Engineer with 7+ years of experience running mission-critical production platforms across banking, telecom, and e-commerce environments. I specialize in designing resilient cloud-native systems on AWS, Azure, and GCP, with deep expertise in Kubernetes, Terraform, and GitOps-driven delivery.I have led observability and AIOps initiatives using Dynatrace, Prometheus, Grafana, and Splunk—driving measurable improvements in MTTR, alert quality, and incident prevention. My work spans progressive delivery strategies (blue-green and canary), release SLOs, automated rollback pipelines, and infrastructure standardization through IaC and configuration management.On the operations side, I focus on security-first platforms (IAM/RBAC, CIS hardening, vulnerability management), disaster recovery design, and multi-region resiliency. I am particularly interested in Internal Developer Platforms and agentic AI for operations—reducing toil while increasing engineering velocity.I thrive in environments where reliability, automation, and business outcomes intersect.
