Dedicated and results-driven DevOps professional with 6+ years of hands-on experience in optimizing and streamlining IT operations. I have successfully added Kubernetes clusters as runners to GitLab, enhancing scalability and build performance. I spearheaded the adoption of GitLab CI/CD and Argo CD for streamlined development workflows, resulting in a 40% reduction in release time. Additionally, I have managed and maintained Kubernetes clusters, ensuring high availability and scalability for containerized applications. I am skilled in implementing rolling updates and automatic scaling to accommodate increased workloads during peak usage periods.

I have received commendation for resolving critical AWS VPC issues, conducted resource allocation and utilization analysis, resulting in a 15% reduction in infrastructure costs while maintaining optimal application performance. I have also streamlined the CI/CD pipeline for Java-based applications using Maven, resulting in a 20% reduction in build and deployment times. Furthermore, I developed a custom Python script to automate routine system backups, enhancing disaster recovery capabilities. I am proficient in implementing proactive monitoring and alerting using Prometheus and Grafana, reducing system downtime by 15%. I have introduced version control best practices with Git, improving code collaboration and traceability. I have also led knowledge-sharing sessions on CI/CD and automation, empowering team members to take ownership of their workflows.

In my previous role as a DevOps Engineer at The HCI Group, I designed and implemented Jenkins-based CI/CD pipelines, demonstrating proficiency in Ansible and Terraform. I collaborated with cross-functional teams to ensure seamless project delivery in an Agile environment. Additionally, I conducted training sessions on CI/CD best practices, empowering team members to take ownership of their pipelines. At Dell Technologies, I successfully migrated high availability web servers and databases to AWS EC2 and RDS with minimum or no downtime. I also implemented essential security tools and deployed MySQL Primary DB and its read replica in a private subnet with multi-AZ for disaster recovery and best practice. I have utilized performance and AWS cloud services to optimize infrastructure scalability, enhance performance, and ensure high availability within the cloud environment.
