⚡ My engineering approach
I learn cloud concepts by building the infrastructure, creating a realistic failure, diagnosing the incident and documenting the fix. My repositories focus on practical evidence rather than theory-only learning.
Learn Concept → Deploy → Break → Troubleshoot → Fix → Document → Improve
🏗️ Highly Available 3-Tier Web Application on AWS — In Progress
Production-inspired architecture designed for availability, security and horizontal scaling.
Users → Route 53 → Application Load Balancer → Auto Scaling EC2 → Amazon RDS
Public Subnets Private Subnets DB Subnets
- Multi-AZ VPC with public and private subnet layers
- Application Load Balancer and Auto Scaling architecture
- Private database tier using Amazon RDS
- Security Group chaining between application layers
- IAM, CloudWatch, S3 and production-oriented documentation
Stack: AWS VPC · EC2 · ALB · Auto Scaling · RDS · IAM · CloudWatch
🧱 Infrastructure as Code with AWS CloudFormation — Completed
- Reusable YAML template for infrastructure provisioning
- Custom VPC, public subnet, routing and internet connectivity
- IAM role and EC2 instance provisioning
- Automated Nginx installation and deployment verification
🖥️ Amazon EC2 + Nginx Web Deployment — Completed
- Linux EC2 deployment with Security Group configuration
- Secure remote administration and Nginx configuration
- Application hosting, service validation and HTTP testing
🐳 Dockerized Nginx Web Application — Completed
- Built a reusable Docker image for an Nginx web application
- Configured port mapping, health checks and HTTP verification
- Documented the complete container build and runtime workflow
| Project | Focus | Status |
|---|---|---|
| Amazon S3 Static Website Hosting | S3 website hosting and bucket access configuration | ✅ Completed |
| Java Cloud Server Health Checker | Java, JSP/Servlet, Tomcat and MySQL CRUD application | ✅ Completed |
| Secure RAG FastAPI Backend | FastAPI, document retrieval and source-grounded responses | 🚧 In Progress |
| Cloud Portfolio | AWS-console-inspired personal portfolio | 🚧 In Progress |
🛡️ Production principles I practise
- Apply least-privilege access instead of broad permissions
- Keep application and database workloads in private network tiers
- Design across Availability Zones where the workload requires resilience
- Monitor system health and document deployment evidence
- Use reusable infrastructure definitions instead of repeated manual setup
