Upgrade your existing basic agents to an advanced AI system using LangChain and LangGraph, with memory and RAG, and production-ready patterns, without starting from scratch.
Explore how agentic AI addresses QA pain points like test authoring and regression triage, enabling autonomous log analysis, self-healing tests, and autonomous test case generation with Lankchain and Lankgraph.
Explore seven common prompt types—instructional, contextual, formatting, open-ended, specific example, clarification, and comparative—and learn to choose the right prompt type for your use case to maximize AI results.
Install Ollama on macOS by downloading the DMG from olama.com and dragging it to the applications folder, or install via brew with brew install OLAMA.
learn to hit Ollama via curl, using the /api and /api/generate endpoints, pass a model and prompt, and format responses with stream or jq for readable JSON.
Learn to call the OpenAI chat completion API with curl, including setting the API key, choosing a model, and extracting content from JSON responses.
Understand Lanchain as an open source framework for building LLM powered applications. Explore how it handles multi-step calls, prompt templates, memory, and external tool integration.
Install Langchain and five dependencies (Langchain core, OpenAI, Google Gen AI, and Langchain community for Olama) by editing requirements.txt, then verify with the test-lanchain-install script and pip list.
[THE ENTIRE COURSE HAS BEEN CREATED IN 2026 APRIL WITH THE LATEST LANGCHAIN AND LANGGRAPH FRAMEWORKS]
Ready to transform your basic agents into production-ready, intelligent systems used by top tech companies?
Welcome to the ONLY course on Udemy that takes your existing AI agents from the beginner level to enterprise-grade systems using Langchain, LangGraph, RAG, Memory, and Multi-Agent orchestration.
The demand for these skills is exploding. Senior QA roles paying $120K - $150K + require Langchain/LangGraph experience. This course gives you that.
Why These Skills Matter in 2026:
Companies hiring AI/ML Engineers for QA teams expect:
✓ Langchain/LangGraph experience (now industry standard)
✓ RAG implementation for proprietary knowledge
✓ Multi-agent orchestration patterns
✓ Production deployment knowledge
✓ Cost optimization and scalability
This course covers ALL of that.
By the End of This Course:
✓ Build production-grade agents with Langchain and LangGraph
✓ Implement RAG for company-specific knowledge retrieval
✓ Create multi-agent systems for complex workflows
✓ Add memory so agents learn from past interactions
✓ Deploy agents that integrate with real QA tools
✓ Optimize costs and performance at scale
✓ Confidently discuss advanced agentic AI in interviews
✓ Have portfolio projects that demonstrate enterprise skills
What Makes This Course Different?
We don't start from scratch. We take the TestCase Generator and Log Analyzer agents you already built and progressively upgrade them with powerful capabilities. Every code change is tracked on GitHub with tags - you can see exactly how your agents evolve from basic to advanced.
You'll Build On Your Existing Code:
In the beginner course, you built agents in the src/agents/ folder using vanilla Python. In this course:
- Section 4: Migrate to Langchain (src/agents_v2/)
- Section 5-8: Rebuild with LangGraph graphs (src/graph/)
- Section 9-14: Add RAG, Memory, and Multi-Agent capabilities
This progressive approach prevents confusion and lets you compare vanilla Python vs frameworks side-by-side.
What You'll Master in This Course:
1. Langchain Framework (Foundation)
Learn the industry-standard framework for LLM applications. Understand chains, prompts, output parsers, and when to use Langchain vs vanilla Python. Migrate your existing agents to Langchain in under 20 lines of code.
2. LangGraph (Main Framework for Complex Agents)
Master stateful, graph-based agent workflows. Build agents with conditional routing, error recovery, retry logic, and human-in-the-loop approval. LangGraph is what production systems use for reliability.
3. RAG & Vector Databases
Stop generating generic outputs. Teach your agents company-specific knowledge using ChromaDB. Implement semantic search to retrieve relevant test cases, logs, and documentation. Your agents will reference YOUR data, not generic internet knowledge.
4. Memory & Context Management
Build agents that remember past conversations and learn from previous interactions. Implement short-term memory (conversation history) and long-term memory (persistent vector storage). Your agents will get smarter over time.
5. Multi-Agent Systems
One agent is good. Multiple specialized agents working together is unstoppable. Learn the Supervisor Pattern where a coordinator agent orchestrates specialist agents (Log Analyzer → Root Cause Investigator → Solution Recommender). Real production systems work this way.
6. Human-in-the-Loop Workflows
Production agents need human oversight. Implement approval nodes where agents pause for human review before taking critical actions. Build feedback loops for iterative refinement.
Real-World Integration:
- TestRail API: Push generated test cases directly to test management
- Jira API: Auto-create bugs from log analysis
- Slack: Send agent reports to team channels
- Webhook Triggers: Start agents from external events
What You Get:
- 7+ hours of advanced hands-on tutorials
- Complete source code on GitHub with tags for every topic
- Side-by-side comparison: Vanilla → Langchain → LangGraph
- Production-ready patterns and best practices
- Real integration examples (TestRail, Jira, Slack)
- Support for the latest Langchain and LangGraph
- Lifetime access and free updates
