🔐 DevSecOps Pipeline with GitLab & OWASP

Created a fully automated GitLab CI/CD pipeline with built-in security gates using Trivy, OWASP Dependency-Check, and Snyk CLI. Used Terraform to deploy secure multi-AZ EKS clusters with IAM roles, secrets scanning, and audit logging.

☁️ AWS Event-Driven Monitoring Stack

Deployed an event-driven Lambda + CloudWatch + SNS stack to monitor EKS pod restarts, unauthorized IAM attempts, and suspicious S3 uploads. Used IAM policy simulation for testing and budget alarms to prevent cost overruns.

🧠 Edge Computing & Network Security Lab (Raspberry Pi 5)

Architected a local edge gateway using Raspberry Pi 5 (16GB) and Ubuntu. Implemented Zero Trust principles with AdGuard Home for DNS filtering, NextDNS for telemetry, and Samba for secure storage. Exposed via drive.psritej.com.
