Work Experience
Site Reliability Engineer
Olive Crypto Systems
- Operated production infrastructure for a bank’s CBDC platform across bare-metal and OpenShift environments, supporting reliable service delivery for a nationally scaled digital currency system handling 3L+ transactions/day.
- Managed Kubernetes/OpenShift workloads including namespaces, deployments, StatefulSets, services, routes, ConfigMaps, Secrets, Helm releases, rolling updates, and failover readiness across 40+ services in UAT, Production, and DR.
- Built and maintained observability using ELK Stack, Prometheus, and Grafana to centralize logs, metrics, dashboards, health checks, and alerts, reducing average incident detection time by 40%.
- Led production release validation across DTSP and RTSP layers using log, metric, and service-health checks to verify deployments and support safe rollback when required.
- Served as an SRE point of contact during critical incidents, coordinating with NPCI, bank infrastructure, network, security, and application teams to restore services within 30-minute SLA.
- Performed root cause analysis for recurring production issues and translated findings into preventive fixes, monitoring improvements, and operational runbooks.
- Automated certificate rotation checks, health checks, log collection, gateway validation, and routine support tasks using Bash, Python, and GitLab CI/CD pipelines, cutting manual effort by 30%.
- Planned and executed backup validation, replication checks, failover testing, and disaster recovery drills across bare-metal, OpenShift, and blockchain nodes.
- Supported server hardening, vulnerability remediation, VAPT closure, access reviews, and secure configuration of production systems within defined compliance timelines.
- Deployed and supported Hyperledger Fabric peer nodes, ordering services, certificate authorities, certificates, and network services with node-level monitoring.
- Participated in on-call rotations, triaged alerts, documented incident timelines, and contributed to blameless post-incident reviews and corrective actions.
- Contributed to Infrastructure as Code and deployment standardization using Terraform, Helm, Git, and GitLab CI/CD.
Projects
AI-Driven Cloud-Native Observability Platform for Kubernetes
- Built a production-inspired SRE platform around a containerized Java microservice with Redis caching, Kafka event streaming, and SQL-backed services deployed on Kubernetes/OpenShift.
- Implemented end-to-end observability with Prometheus, Grafana, Loki, Promtail, ELK Stack, and Elastic APM for metrics, logs, dashboards, tracing, and application performance monitoring.
- Configured Prometheus service discovery, metric scraping, alert rules, SLI/SLO monitoring, and Alertmanager notifications for Slack, Microsoft Teams, email, and PagerDuty.
- Built Grafana dashboards for Kubernetes cluster health, JVM metrics, application latency, error rates, pod resource usage, and availability indicators.
- Implemented Loki and Promtail for label-based Kubernetes log aggregation from application pods and cluster nodes, while using ELK for search, RCA, and operational analysis.
- Automated deployments using Helm, Terraform, and GitLab CI/CD while managing Deployments, StatefulSets, Services, Ingress, ConfigMaps, Secrets, RBAC, Persistent Volumes, and HPA.
- Designed AI-assisted workflows for anomaly detection, predictive alerting, root cause analysis, and automated remediation using observability data.
- Validated resilience through liveness/readiness probes, rolling updates, horizontal scaling, backup checks, and disaster recovery testing.
