Durgesh Singh

Cloud & DevOps Engineer with expertise in AWS, OpenStack, OpenShift, Linux, Kubernetes, and CI/CD automation. Adept at designing and managing cloud infrastructure, monitoring solutions,and containerized deployments. Passionate about DevOps automation, cloud security, and site reliability engineering (SRE).

OpenStack Infrastructure Management
 Managed OpenStack infrastructure across compute, storage, and networking services,
ensuring 24/7 availability.
 Integrated monitoring tools like Grafana, Kibana, and Prometheus for 70+ Pan-India
sites.
 Expanded compute, KVM, and Ceph nodes on live sites, following proper CR and
incident timelines.
 Configured and monitored virtual machine (VM) health and performance using
Prometheus and custom exporters.
 Performed OpenStack upgrades and migrations with minimal downtime, ensuring
seamless service continuity.
 Automated routine tasks and system upgrades to enhance operational e􀆯iciency.
 Collaborated with cross-functional teams to troubleshoot performance bottlenecks in
Nova, Neutron, and Cinder services.
 Validated MBSS documents for the H-Cloud Project while implementing security
hardening concepts.
 Managed and configured backups for all sites using the Commvault backup tool.
Monitoring and Observability
 Deployed and maintained monitoring tools (Prometheus, Thanos, Grafana) for real-time
observability and long-term metrics storage.
 Integrated Thanos for scalable and centralized metric queries across distributed
Prometheus instances.
 Utilized Prometheus CLI query language and Kibana to advance AI/ML use cases.
 Performed all testing and alert configuration for site expansions and new node
validations.
 Created custom dashboards and set up alerts for critical infrastructure metrics.
Site Expansion Projects
 Led site expansion projects by provisioning compute and storage resources using Heat
templates and manual orchestration.
 Validated and tested newly expanded nodes to ensure optimal performance and
reliability.
Incident and SLA Management
 Created and resolved TTs (Trouble Tickets) and CRs (Change Requests) for all issues and
activities, ensuring compliance with SLA.
 Monitored and ensured the timely delivery of health checkup reports using Python and
Linux scripting.
OpenShift and Container Management
 Managed multiple projects within OpenShift, handling resource allocation and scaling
for services and pods.
 Created, updated, and deleted ConfigMaps and Secrets to manage dynamic application
configurations.
 Integrated Prometheus and Grafana for real-time monitoring and improved cluster
observability.
 Troubleshot pod failures and network issues, achieving 99.9% application uptime.
 Monitored pod health and resolved performance issues using OpenShift Web Console
and CLI tools.
 Contributed to automation scripts for container builds, deployment rollbacks, and log
collection.
Data Analytics and Reporting
 Integrated multiple network components in the NLM project using data analytics and
Excel skills on Logstash and Elasticsearch.
 Utilized advanced data analysis techniques to ensure accurate insights and system
performance.
