Ronik Singh

DevOps Engineer at Infosys Limited (2022-12 – Present)

Provisioned and managed Azure infrastructure — VMs, VNets, AKS clusters, storage — using Terraform and ARM/Bicep, maintaining reusable modules across dev, staging, and production for consistent, repeatable environment setup.
Deployed and operated containerized workloads on Azure Kubernetes Service (AKS): handled rollouts, autoscaling, node/pod-level troubleshooting, and Helm-based release management.
Built and maintained CI/CD pipelines in Azure DevOps (YAML) and GitHub Actions across multiple services, with PyTest gates holding coverage above 85% before anything reached production.
Owned day-to-day on-call and incident response — monitored Azure Monitor and Grafana dashboards, triaged alerts as they came in, and wrote Python/Bash scripts to auto-diagnose and fix recurring infrastructure issues, bringing MTTR down to under 20 minutes.
Diagnosed a recurring database connection bottleneck under peak load and fixed it by introducing PgBouncer connection pooling with autoscaling rules — cut backend response times by 40% and eliminated repeat incidents during traffic spikes.
Set up Redis caching in front of high-traffic services to cut database load by roughly 60%, reducing how often the on-call rotation got paged.
Wired SAST/DAST scanning into CI/CD and enforced Azure Policy guardrails to catch vulnerabilities and misconfigurations before production; centralized logging/alerting (Azure Monitor, ELK) with least-privilege IAM/RBAC codified through Terraform.
