In 2 months you will learn:
Instruction files for the agent
Bug reports, CLAUDE.md, path-scoped rules in .claude/rules/, compatibility with AGENTS.md, and organising memory between sessions. Plans, reports, and team updates — powered by AI.
Context engineering
Managing what enters the session context, compressing it, and using subagents to isolate context.
An automated verification loop for code
Types, linters, unit, integration, and e2e tests, plus a CI gate, built into a single sequence with an understanding of which errors each level detects.
Access control and agent security
Operating modes, deny/ask/allow, sandbox, hook guards, and mandatory human confirmation of irreversible actions.
Reviewing AI-generated code
Reading the diff, verifying the agent's evidence and claims instead of trusting its report, recording unresolved risks.

How AI programming courses differ from Claude Code for Devs
AI programming courses usually teach you to write code with AI tools from scratch or at a basic level. Claude Code for Seniors is designed for developers who regularly ship production code without AI, and teaches not just how to write code with AI, but how to review agent-generated code and take responsibility for its quality in production.
The best AI for writing code – and who answers for the result
The search for the best AI for writing code often comes down to choosing a tool. But choosing an AI assistant is only part of the job. The main question is who reviews the code generated by the agent and how to detect an error before it reaches production. Claude Code for Seniors teaches you to build exactly this verification loop: types, linter, unit and integration tests, e2e, a CI gate, and production monitoring.
Why AI will not replace frontend and senior developers
An AI agent, including Claude Code, generates code — frontend code too — but responsibility for the result remains with the developer. Claude Code for Seniors teaches you to build a verification loop for AI-generated code, recognise typical agent mistakes, and check the result of its work rather than relying only on its report. Whether it is frontend or backend.
Who is the Claude Code for Devs course for?
The course suits developers with 3+ years of commercial experience who regularly ship production code and are used to working independently – handling incidents themselves, agreeing changes with a reviewer, estimating tasks. English at Pre-Intermediate level or above is required.
