Secure software delivery reference pipeline that hard-blocks on SAST, secrets, and CVE scans, signs and attests every image with Syft/Cosign, and enforces signature and policy checks at Kubernetes admission via Kyverno — with Terraform drift detection and every control mapped to NIST 800-53.

Full-stack cargo entry screening system simulating a port-of-entry workflow — importers file manifests, a risk engine flags shipments, and officers/supervisors review and track them through an Angular console backed by a Spring Boot REST/SOAP API and PostgreSQL, deployable via Docker Compose, Kubernetes, or Terraform-provisioned AWS (ECS Fargate + RDS + ALB).

Sensor-telemetry ingestion and analytics platform that joins an existing field-sensor deployment mid-stream — idempotent ingestion, rolling-window anomaly detection and alerting, a documented REST API, a React operator dashboard, and a C#/.NET notifier consuming that same API as a second-language client, deployed live to AWS via Terraform.
