Experience
Application Designed and Deployed on OpenShift, Kubernetes
I optimized the VM creation process (with all software and post-configuration deployed) from days to minutes. By this, I saved tremendous manual effort and saved money for the company. The client was very happy about the results.
DevOps Specialization
My experience includes building optimized Dockerfiles, managing container images through ECR, and implementing secure CI/CD pipelines. I've worked extensively with RDS and other AWS managed services to design scalable and resilient architectures. I also bring experience in deploying PHP applications and integrating multiple third-party services seamlessly. Additionally, I've implemented data masking and security best practices to ensure compliance and protect sensitive information across all environments.
