You miss things. You always miss things.” Manual security group reviews feel fine at one account. At ten, you’re genuinely flying blind — too many rules, too much context to hold in your head, no audit trail. I built this CLI tool to close that gap. This is the breakdown: what I built, the failure modes I hit, and what the production version actually looks like.https://dev.elijahu.me/portfolio/projects/orchestration-guide/Sat, 01 Mar 2025 00:00:00 +0000https://dev.elijahu.me/portfolio/projects/orchestration-guide/“Manual deployments are technical debt with compound interest. Every time you run kubectl apply by hand you’re borrowing against future reliability.” This is a full breakdown of a push-to-deploy GitOps pipeline on Kubernetes — Flask webhook orchestration server, isolated test namespace with resource quotas, RBAC scoped to minimum permissions, network policy isolation between test and production, and blue-green deployment with automated rollback. Built because the manual process was unsustainable, documented because the failure modes are worth knowing.https://dev.elijahu.me/portfolio/projects/numberapi/Wed, 05 Feb 2025 00:00:00 +0000https://dev.elijahu.me/portfolio/projects/numberapi/“Serverless removes the infrastructure management problem and replaces it with a different set of problems. CORS is one of them.” This is a breakdown of a number classification API built on AWS Lambda with API Gateway — the architecture decisions, the full Lambda function with input validation and error handling, the CORS preflight issue that catches most people, and the edge cases worth thinking about before they hit production.
