Welcome to my AWS Security & Networking portfolio — a collection of real, deployed, security-focused cloud projects built using Terraform and validated directly in the AWS Console.
This repository demonstrates hands-on experience in:
- Secure network architecture
- Identity & access governance
- Detection & analytics pipelines
- Serverless security
The main portfolio folder contains multiple production-relevant projects:
📂 aws-security-networking-portfolio/
Inside it you’ll find:
Hub-and-spoke VPC design with centralized inspection and egress control.
Focus: Transit Gateway, AWS Network Firewall, VPC Flow Logs.
Identity governance with permission boundaries, break-glass access, and CloudTrail alerting.
Focus: IAM policies, roles, least privilege.
Security telemetry pipeline with GuardDuty, Security Hub, EventBridge, and OpenSearch.
Focus: Detection engineering and alert automation.
API Gateway + Cognito + WAF with private Lambda and VPC endpoints.
Focus: Application security and serverless best practices.
This repository includes verified AWS console screenshots that prove real infrastructure deployment.

Validated components include:
- VPC security groups and networking
- IAM policies and service roles
- Lambda functions with SQS triggers
- API Gateway POST endpoints
- Amazon RDS (PostgreSQL)
- Amazon Athena queries over S3 data
These artifacts demonstrate that the projects are deployed, tested, and observable.
