Docker
Package apps so they run the same everywhere.
DevOps Engineer
AWS, Docker, Kubernetes, CI/CD, and Infrastructure Automation
I am Ajay Kumar, a DevOps engineer focused on building secure, scalable, and production-ready cloud platforms with strong reliability and release performance.
Professional Summary
DevOps Engineer with 3+ years of experience in designing, automating, and operating AWS cloud infrastructure and CI/CD platforms. Strong hands-on experience in AWS (EC2, IAM, VPC, S3, EKS, ECR, ECS, ALB, CloudWatch), Terraform, Docker, Kubernetes, and Jenkins. Skilled in Infrastructure as Code, container orchestration, monitoring, and security best practices.
What I Work With
Kubernetes
Run and scale containers automatically.
Jenkins / GitHub Actions
Automate build, test, and deploy.
Terraform
Create cloud infrastructure using code.
AWS
Host and scale applications in the cloud.
How a DevOps Pipeline Works
When a developer pushes code to Git, a pipeline builds the app, creates a Docker image, deploys it to Kubernetes, and monitors it automatically.

Monitoring
My Sample DevOps Project
Automated CI/CD for a Web App
- Code stored in GitHub.
- Jenkins builds and tests the app.
- Docker creates the image.
- Kubernetes deploys with zero downtime.
- Prometheus and Grafana monitor the app.

DevOps Concepts in Simple Words
CI
Automatically testing code after every change.
CD
Automatically deploying tested code.
Container
A lightweight box that contains the app and dependencies.
IaC
Creating servers using code instead of clicking.
Rolling Update
Update the app without downtime.
Why DevOps?
DevOps helps teams release software faster, safer, and with fewer failures by automating repetitive tasks and improving collaboration.
