About

Highly skilled DevOps Engineer with over 5 years of hands-on experience, I specialize in cloud-native technologies and infrastructure automation. My expertise encompasses designing and optimizing CI/CD pipelines, leveraging tools such as Jenkins, GitHub Actions and ArgoCD. I am adept at implementing robust monitoring solutions with Prometheus, Grafana, and the ELK Stack, ensuring system reliability and performance. With a lot of experience in Cloud Security, my knowledge of Microsoft Sentinel and Defender for Cloud gives me an Edge in adopting security into CI/CD pipeline. Implemented a GitOps workflow using ArgoCD to automate the deployment of microservices to a Kubernetes cluster Achieved a 96% cost reduction for 80 ETL pipelines by migrating from AWS Glue to a self-managed Apache Airflow environment. This involved deploying Airflow on EC2 instances within an ECS cluster, orchestrated via Terraform. The migration decreased monthly infrastructure costs from $10,000 to $400, without compromising on performance.
