Systems Design Interview & Architecture Guide
System design interview prep and architecture guide for DoD/Coast Guard IL2/IL4 environments on AWS GovCloud. Covers designing scalable, secure, compliant systems using EKS, PostgreSQL (RDS), Terraform, FluxCD, Prometheus/Grafana, and AWS managed services. Use this skill whenever someone is preparing for a system design interview, architecting a backend system, discussing database design or PostgreSQL patterns, planning Kubernetes deployments, designing for high availability or fault tolerance, evaluating replication or sharding strategies, working on CI/CD pipelines, discussing observability, or making any architecture decision. Also trigger when someone mentions: data modeling, scaling, load balancing, caching, message queues, event-driven architecture, microservices, API design, or compliance requirements (IL2, IL4, FedRAMP, STIG, CUI, ATO). Even casual questions like "how would you design X" or "what database should I use" should trigger this.
