IaC definitions for the foundational infrastructure behind a static website: an S3 bucket with public static hosting, a CloudFront distribution serving the bucket over HTTPS, a Route 53 hosted zone, and an ACM certificate with automated DNS validation. Provided in three equivalent IaC flavors (CDK, Terraform, CloudFormation). This is the base layer that static-website-codepipeline/ deploys into.
A full AWS CodePipeline definition for static site deployment, provided in three equivalent IaC flavors (CDK, Terraform, CloudFormation). Implements a five-stage pipeline: Source → Staging → Manual Approval → Production → Cleanup. The cleanup stage invokes the two Lambdas below in sequence.
Lambda function that scans an S3 bucket and stamps Cache-Control: max-age=31536000 on static assets (images, icons, SVGs). Runs as a CodePipeline action or standalone. Necessary because S3 deploy actions don't set per-extension cache headers on upload.
Lambda function that creates a wildcard cache invalidation (/*) on a CloudFront distribution. Runs as a CodePipeline action or standalone. Ensures users see the latest content immediately after a deploy rather than waiting for TTL expiry.
Lambda function that fetches Google PageSpeed Insights scores for a list of URLs and publishes them as custom CloudWatch metrics. Runs as a post-deploy benchmark in website pipelines, snapshotting Lighthouse scores (accessibility, best practices, performance, SEO) for both mobile and desktop strategies.
IaC definitions for a serverless visit counter: an API Gateway REST API with direct DynamoDB service integrations (no Lambda). GET /visit increments the counter, GET /count reads it back. CORS is scoped to a single allowed origin. Provided in three equivalent IaC flavors (CDK, Terraform, CloudFormation).
Lambda function that checks a stock price against a target, calculates the distance, and sends an SNS notification with the update and a random quote. Designed to run on a daily EventBridge schedule, skipping NASDAQ holidays. Provided in three IaC flavors (CDK, Terraform, CloudFormation) that provision the Lambda, IAM role, and EventBridge schedule.
Lambda function behind an HTTP API Gateway (v2) that lets anyone with the URL send you an SNS notification. A simple public "ping me" endpoint with no auth. Provided in three IaC flavors (CDK, Terraform, CloudFormation) that provision the Lambda, API Gateway, SNS topic, and IAM role.
Minimal JavaScript snippet that converts vertical mouse wheel input into horizontal scrolling. Intended for elements with overflow-x: scroll and overflow-y: hidden where traditional mouse wheels would otherwise be useless. No dependencies, no build step.
GitHub Actions workflows for build, test, and release automation. Currently contains:
macos-app-release/— Builds, archives, and publishes a macOS app as a GitHub Release (.dmg+.zip) on version tag push.
