Sai Krishna

I’m a DevOps Engineer with 2+ years of hands-on experience deploying, maintaining, and monitoring secure, scalable AWS infrastructure. I focus on automating operational and infrastructure tasks to reduce manual effort and increase delivery speed—without compromising security. I’ve built and maintained CI/CD pipelines and authored 200+ Bash and Python scripts to keep systems reliable at scale.

In my current role as an AWS DevOps Support Engineer at Teleperformance, I manage AWS services like EC2, S3, IAM, VPC, ALB, CloudWatch, Lambda, and ECS, achieving 99.9% uptime while reducing manual configuration effort by 40%. I build CI/CD pipelines with Jenkins and GitHub Actions, integrating Maven builds and SonarQube quality gates to deliver 8–10 releases per month and cut release cycle time by 30%. I also engineer IAM policies and governance controls aligned with AWS security best practices, enforcing least-privilege access and supporting security audits with zero findings across quarterly reviews.

I bring strong container and orchestration capabilities, containerizing 30+ microservices with Docker and orchestrating deployments on Kubernetes and AWS ECS using rolling updates, health probes, and auto-scaling policies. I monitor reliability and performance using CloudWatch, CloudWatch Logs Insights, Prometheus, and Grafana, resolving 250+ production incidents and reducing MTTR by 25%. I’m equally comfortable in Linux administration and security-hardening, and I document runbooks and SOPs in Confluence to accelerate onboarding and deployment consistency.
