  INSTRUCTOR(S)
  HEADLINE
    Master LangChain, LangGraph, RAG & Multi-Agent Systems. Build
    AI-powered QA workflows and an AI QA Copilot for testing
  WHAT YOU'LL LEARN
  * Build production-grade AI applications in TypeScript using
    LangChain and Anthropic's Claude models
  * Master LCEL (LangChain Expression Language) to compose
    chains,
    run steps in parallel, and stream responses
  * Generate reliable, type-safe structured output using Zod
    schemas and Claude's tool-calling API
  * Create custom tools that let an LLM read files, call APIs,
    run
    shell commands, and drive a browser
  * Build complete RAG pipelines with document loaders, chunking
    strategies, embeddings, and ChromaDB
  * Improve retrieval quality with metadata filtering, multi-
    query
    retrieval, re-ranking, and compression
  * Debug, trace, and cost-monitor every LLM call using
    LangSmith
  * Run automated evaluations on prompts ? regression testing
    for
    AI, using skills you already have as a QA engineer
  * Prototype AI workflows visually with Langflow and export
    them
    as working APIs
  * Integrate Playwright with LangChain to generate specs and
    self-heal broken selectors
  * Understand why simple agents fail ? and use LangGraph to
    build
    stateful, cyclic, multi-actor systems instead
  * Implement human-in-the-loop approval gates, checkpointing,
    and
    durable agent state
  * Build a full Autonomous QA Agent: explores an app, plans
    tests, writes Playwright specs, runs them, diagnoses
      failures,
    and heals itself in a loop
  REQUIREMENTS
  * Experience with any test automation framework (Playwright,
    Selenium, Cypress) is helpful but not required
  * Typescript basics is covered from the scratch in the course
  * Free accounts for LangSmith and ChromaDB (local install, no
    cost)
  * No prior AI, machine learning, or Python experience needed
  WHO IS THIS COURSE FOR
  * Anyone who wants to learn LangChain and build autonomous AI
    Agents
  * SDETs who want to build AI-powered testing tools
  * QA automation engineers transitioning into AI/ML engineering
  * TypeScript/JavaScript developers learning LangChain without
    switching to Python
  * Test leads evaluating AI agents for their team
  * Anyone who knows TypeScript and wants to build real
    autonomous
    agents, not chatbot demos
  DESCRIPTION
  Every QA automation engineer is asking the same question right
  now: how do I move into AI before AI moves past me? This
    course
  is the answer ? and it's built specifically for you, not for
  Python data scientists. You already understand test
    frameworks,
  assertions, CI pipelines, and debugging flaky systems. Those
    are
  exactly the skills AI engineering needs. What's missing is the
  LangChain layer ? and that's what you'll build here, entirely
    in
  TypeScript, using Anthropic's Claude models. We start from
  absolute zero on LangChain. Your first API call. Your first
  chain. Your first tool. Then we go all the way to a multi-
    actor
  autonomous agent with cycles, persistent state, and human
  approval gates. What makes this course different Most
    LangChain
  courses stop at a chatbot. This one is built for real testing
  workflows. By the end, you will design and build an AI QA
  Copilot ? a practical LangGraph-powered system that can:
    Answer
  questions from requirements and SRS documents using RAG
    Generate
  structured test cases from user stories Create test data for
  automation scenarios Use tools and MCP servers for reusable QA
  utilities Coordinate multi-agent workflows like Generator,
  Reviewer, and Supervisor Apply memory, routing, and guardrails
  for more reliable agent behavior This is not just theory. This
  is a portfolio-ready AI testing project you can showcase in
  interviews and real QA work. You'll also master the tools
    teams
  actually pay for LangSmith isn't an afterthought here ? you'll
  use it from Section 8 onward to trace every agent decision,
  catch failures, and run prompt evaluation suites. As a QA
  engineer, you'll recognize it immediately: it's regression
  testing for LLMs. VectorDB powers a real RAG project ? a
  searchable knowledge base over your own test suite, so you can
  ask "do we already have a test for this?" Multi-Agent systems,
  Orchestration & Guardrails and many more practical concepts
  Honest expectations You'll see agents fail. We walk through
    what
  breaks, why it breaks, and how to build guardrails around it.
  Non-determinism is uncomfortable for testers ? we address that
  directly instead of pretending it away. By the end, you'll
    have
  shipped multiple working projects and one capstone that very
    few
  engineers can demo. Enroll now and start building.
