Udemy – Claude Code for Developers: Real Codebases, Real Workflows

Most AI coding courses show someone building a toy app in an empty folder. Your job does not look like that. You inherit services other people wrote. You fix bugs under time pressure. You review code before it ships to production, where mistakes cost money. This course teaches the missing skill: how to use Claude Code, Anthropic’s AI coding agent, on real software, with the discipline of a senior engineer.

You will spend the entire course inside ShopFlow, a deliberately imperfect .NET 8 e-commerce backend with three services, a God class, a race condition, a memory leak, swallowed exceptions and missing tests. Every flaw is planted on purpose. Every flaw becomes a lecture.

What you will learn to do:

• Drive the senior engineer loop: plan, constrain, generate, verify
• Teach Claude your codebase with a CLAUDE-md memory file file and manage context like a budget
• Map an unfamiliar codebase in fifteen minutes and generate docs that stay true
• Ship production features: CRUD endpoints, JWT auth, validation, hardening
• Refactor a 900-line God class safely behind a characterization-test gate
• Generate tests that test behavior, not implementation: unit, integration, Playwright
• Debug like a pro with an agent: exception storms, race conditions, deadlocks,
