About

I began my career as a Software Configuration Management (SCM) and Release Engineer, where I gained a strong foundation in build automation, version control, and release management. Over time, I transitioned into DevOps through self-learning and hands-on experience, focusing on improving software delivery processes and automation. I have solid expertise in Jenkins for building CI/CD pipelines, including DevSecOps integrations that ensure security is embedded throughout the delivery lifecycle. My experience also includes using tools like IBM UrbanCode Deploy, Docker, and Kubernetes for containerization and orchestration. In recent years, my work has evolved toward Site Reliability Engineering (SRE) and Platform Engineering, where I focus on creating scalable, reliable, and automated systems. I work extensively with Terraform on GCP for Infrastructure as Code, and have a growing interest in observability, monitoring, and performance optimization to improve platform resilience and developer productivity. I’m passionate about building reliable and secure platforms through automation, observability, and continuous improvement — ensuring both speed and stability in every delivery.
