Don't let this gap widen
Why this program matters
Without expert mastery of LangChain, 70% of AI projects fail in the scaling phase according to Gartner, multiplying development costs by 3 and delays by 2.
Your pipelines remain slow, imprecise, exposed to costly hallucinations in production – imagine losing 40% ROI on a faulty client chatbot.
Competitors chaining agents and RAG capture 25% more market share.
Risk of developer burnout from time-consuming manual hacks, and rapid obsolescence against LLM updates.
Invest 28 hours to transform these losses into exponential gains: x5 productivity, robust apps, affirmed AI leadership.
Program
Module 1Advanced LangChain Chains: LCEL, Parsers and Tools (Practical Exercises)
Dive into LCEL to assemble fluid chains, handle JSON and Pydantic parsers for structured outputs, integrate ready-to-use tools like Wikipedia or calculators, complete exercises on real Q&A cases, produce your first production-ready functional pipelines, and test live with LLMs like GPT-4.
Module 2LangChain Agents: Creation, Custom Tools and Reasoning (Agent Deliverables)
Create ultra-performant ReAct and OpenAI Functions agents, develop custom tools via @tool for web scraping or data analysis, simulate multi-agent collaborative scenarios, refine reasoning with concrete task automation examples, generate deployable agents ready for immediate use, and measure their effectiveness in real conditions.
Module 3LangChain RAG and Memory: Optimized Retrieval, Embeddings (Case Studies)
Master RAG with vector stores like FAISS or Pinecone, integrate advanced embeddings for precise semantic retrieval, manage conversational and episodic memory for persistent interactions, apply to real business datasets like customer support, produce custom RAG chains, and evaluate accuracy with metrics like ROUGE.
Module 4LangChain Deployment and Scaling: Monitoring, Best Practices (Final Project)
Deploy on FastAPI, Streamlit or LangServe for scalable apps, implement callbacks for logging and tracing with LangSmith, optimize for production with async and batching, debug common errors via observability, complete a full-stack AI agent capstone project, and leave with a cloud-deployed portfolio.
Evaluation method
- Daily interactive quizzes, Practical projects per day, Final evaluation on real business case with personalized feedback.
Learning method
- 70% hands-on real code, 30% applied theory, Exercises with open-source datasets and live APIs.

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.
Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
