muralidharan666666-dev/README.md

Hi, I'm Muralidharan M N

AWS Certified Cloud Practitioner (CLF-C02) · AWS re/Start Graduate

Building real, end-to-end AWS infrastructure — and documenting every build and every bug I fix along the way.

I'm an aspiring Cloud Engineer with hands-on AWS projects spanning networking, serverless, containers, and event-driven architecture. Each one was built, broken, debugged, and documented independently — the READMEs walk through the real errors I hit and how I traced them to root cause. Previously in banking and financial services; now focused on a cloud career.

Featured Projects

Project What it demonstrates Key AWS services
Three-Tier Web Application High-availability VPC design, layered security, auto scaling VPC, EC2, ALB, RDS Multi-AZ, Auto Scaling, Systems Manager
Serverless Tasks API Secure serverless REST API with auth + edge protection Lambda, API Gateway, DynamoDB, Cognito, WAF
Microservices on ECS Fargate Independent microservices, path routing, fault isolation ECS Fargate, Docker, ECR, ALB, DynamoDB
Event-Driven Order Processing Decoupled async pipeline with retries + dead-letter queue API Gateway, Lambda, SQS, SNS, DLQ

Each repo includes an architecture diagram, real test results, and a documented troubleshooting section.

Tech I Work With

  • Cloud: AWS — EC2, S3, VPC, IAM, Lambda, RDS, API Gateway, DynamoDB, ECS Fargate, CloudFront, CloudWatch, SNS, SQS, Cognito, WAF
  • Tools: Docker, Git/GitHub, Linux, Bash, Python (basics)
  • Practices: Least-privilege IAM, network segmentation, monitoring & alerting, root-cause troubleshooting
