Serverless URL Shortener

Production-style link shortener running entirely on AWS with zero always-on servers: Lambda + API Gateway + DynamoDB, deployed with SST infrastructure-as-code in one command. Supports custom vanity codes, self-expiring links via native DynamoDB TTL, atomic click counters, per-IP rate limiting without Redis, and structured logs with CloudWatch metrics — designed to serve 1M+ redirects a month for under $5. Includes a hand-styled React + Vite demo UI and a fully mocked Vitest suite.
