This repository is a small Java collection of programming exercises, not a single integrated product. Its principal demonstrated workflow is the app entry point constructing a customer lookup service, which detects an identifier format, normalizes phone numbers when needed, and asks a repository for an employee result. Separate examples cover employee data and analytics, synchronized counting, and per-user rate limiting. The app also contains employee and concurrency demo methods; the excerpt shows their calls, though not that they are run. Rate limiting is implemented but no runtime caller is shown.
