Three projects for your GitHub profile, each built the same way. Read the guide, run the starter’s tests (they all fail), and write the code until they pass. The tests tell you when each milestone is done.

WHAT IS INSIDE

• A 32-page PDF build guide: for each project, scope, design, six milestones with specs and hints, a CI workflow and a README template.
• Three starter repos with the full test suite already written, 361 tests in total:

1. Webhook Playground (Python, FastAPI, SQLite): HMAC signatures, duplicate events, safe replay. 44 tests.
2. API Uptime Board (TypeScript, Vitest, Chart.js): timeouts, percentiles, incidents, URL validation. 139 tests.
3. Evidence Job Tracker (Next.js, PostgreSQL, plain SQL): status rules, transactions, row locks. 178 tests against a real database.

HOW IT IS CHECKED
Each test suite was run against a working solution, and bugs were introduced on purpose to confirm the tests catch them. A separate AI reviewer then completed each project from the guide and starter alone, and the problems it found were fixed.

WHAT IT IS NOT

• No solutions are included.
• No promise of interviews or jobs. It gives you finished, tested, documented projects.

YOU NEED
Git, Python 3.11+ (project 1), Node 22 (projects 2 and 3), and Docker or a local PostgreSQL 16 (project 3).
