Associate Software Engineer – DevOps & Automation
Bosch Global Software Technologies Ltd.
- Architected multi-stage CI/CD pipelines using Jenkins Freestyle & Declarative Pipelines, reducing manual build activities by approximately 40% and accelerating release cadence.
- Integrated GitHub repositories with Jenkins via webhooks & PAT-based authentication, enabling fully automated build execution triggered on every code commit.
- Built Docker-based standardised build environments ensuring reproducible software builds and eliminating dependency inconsistencies across development and QA teams.
- Developed Python automation scripts for smoke testing & validation, reducing QA feedback cycles by approximately30% and catching regressions earlier in the pipeline.
- Configured Prometheus monitoring and Grafana dashboards for CI/CD pipeline observability — build health, throughput, failure rates, and operational alerting.
- Deployed and managed Kubernetes workloads using Deployments, Services, liveness/readiness probes, ConfigMaps, Secrets, and rolling update strategies for zero-downtime releases.
- Configured Horizontal Pod Autoscaler (HPA) for dynamic scaling of containerised workloads based on CPU and memory utilisation metrics.
- Administered Ubuntu & RHEL servers — toolchain management, environment configuration, user permissions, and shell scripting for build infrastructure.
- Performed root cause analysis (RCA) for recurring pipeline and infrastructure failures, documenting corrective and preventive actions to reduce repeat incidents.
- Collaborated with development, QA, and release teams to troubleshoot build failures, deployment blockers, and environment-specific issues throughout release cycles.
- Maintained internal runbooks, deployment SOPs, and knowledge-base documentation for engineering teams.
Infrastructure & DevOps Support Analyst
Cognizant Technology Solutions
- Delivered L1/L2 infrastructure support for enterprise storage platforms including Pure Storage, Dell EMC PowerMax , and Isilon NAS environments across multiple regions.
- Maintained 99.9% SLA compliance for mission-critical enterprise production environments, ensuring high availability and minimal service disruption.
- Managed deployment and release activities through ServiceNow-based change management workflows; participated in Change Advisory Board (CAB) reviews.
- Performed infrastructure monitoring, log analysis, event correlation, and proactive incident investigation to detect and remediate issues before user impact.
- Automated repetitive operational tasks using Python and Bash scripting, significantly reducing Mean Time To Resolve (MTTR) for recurring incidents.
- Participated in major incident management, coordinating cross-functional teams for rapid isolation, escalation, and resolution of production issues.
- Conducted post-incident reviews and contributed preventive action plans to continuously improve service reliability and reduce recurrence of known issues.
- Created and maintained comprehensive operational documentation: SOPs, troubleshooting guides, and knowledge-base articles for L1/L2 support teams.
Projects
AI-Powered DevOps Monitoring Platform
- Designed a production-grade microservices monitoring platform on Kubernetes using Deployments, Services, ConfigMaps, Secrets, and Helm charts for repeatable, version-controlled releases.
- Implemented self-healing via liveness/readiness probes andHPA for automatic horizontal scaling; applied RBAC, namespace isolation, and secret management for security hardening.
- Built end-to-end observability with Prometheus metrics collection and custom Grafana dashboards for CPU, memory, pod lifecycle, and cluster health monitoring.
- Diagnosed and resolved complex Kubernetes issues including CrashLoopBackOff errors, inter-pod networking failures, TLS certificate errors, and API server instability.
End-to-End CI/CD Pipeline – Azure DevOps
- Built a multi-stage YAML CI/CD pipeline (Build → Test → Deploy) with environment approval gates and Azure Boards integration for Agile sprint traceability.
- Implemented GitFlow branching strategies to enforce code quality gates before merge and deployment; reduced build-failure turnaround time by approximately 35%.
GitHub Actions Automated Deployment Pipeline
- Developed a GitHub Actions workflow to auto-build Docker images and deploy to Kubernetes with rolling updates and readiness-probe health checks for zero-downtime deployments.
- Integrated Prometheus & Grafana for post-deploy observability; enforced image versioning, registry tagging, rollback capability, and smoke test execution as pipeline gates.
