Who this course is for

For developers and engineers who want to move beyond ready-made AI tools and build their own production-ready LLM-based products – with custom MCPs, RAG, and agents, plus testing agents, handling security, running FinOps, and setting up Observability.

Roles

Backend, Frontend, and Fullstack engineers, AI/ML engineers, and tech leads with at least 2 years of professional development experience.

Situations
  • I took the [AI-Driven Development]: Level 1 course and I want to go further – not just use ready-made tools, but build my own.
  • We're building our own AI product with blackjack and agents.
  • I need to roll complex AI features (agents, RAG, custom MCPs) into an existing product.
  • I want to move AI prototypes out of Jupyter notebooks into reliable production – with observability, token cost control, quality assurance, and security.

What you'll gain

AI solution architecture
  • Multi-agent systems: designing architectures with multiple agents, splitting roles, and sharing context between them.
  • Orchestration: the supervisor pattern, ReAct, and Agentic flows – planning loops and autonomous routing between steps.
  • Hybrid designs: choosing the right architecture for the job and moving from a product prototype to enterprise scale.
Stack and tools
  • Custom MCPs: your own MCP servers in Python or TypeScript to integrate LLMs with any internal infrastructure.
  • RAG and CAG: building vector databases (Qdrant), embeddings, prompt caching, and context management.
  • The 2026 stack: Python/TypeScript, LangChain, LangGraph, Qdrant, n8n, Langfuse, Temporal, OpenAI API.
Production practices
  • Evals: approaches to testing LLM pipelines, LLM-as-a-Judge, and synthetic datasets.
  • Observability: agent tracing in Langfuse, monitoring model quality and behavior in production.
  • FinOps: controlling API spend, setting limits, the economics of an AI feature, and alerting.
  • Security: defending against prompt injections, data leaks, and setting up RBAC for agents in a corporate environment.
  • Common mistakes and misconceptions: a breakdown of the typical pitfalls when taking LLM features to production – from "hallucinations can be fixed with a prompt" to underestimating cost and security risks.

Course goals

1. Design multi-agent architectures

ReAct, the supervisor pattern, and complex hybrid designs for scaling AI solutions to enterprise level.

2. Manage model context

Cache prompts (CAG) and build RAG systems on local vector databases – so the model works reliably with internal knowledge.

3. Build your own MCP servers

Write your own MCPs in Python or TypeScript to connect LLMs to any internal infrastructure – local databases, scripts, and internal APIs.

4. Code autonomous agents

From an n8n prototype to production code on LangGraph: memory, state, planning loops, and autonomous routing between steps.

5. Build RAG and CAG infrastructure

Stand up local vector databases (Qdrant), prepare a document corpus, compute embeddings, and tune prompt caching for production workloads.

6. Test LLM pipelines

Evals, LLM-as-a-Judge, synthetic data – ship AI to production with quality guarantees, not just gut feel.

7. Roll out Observability and FinOps

Agent tracing in Langfuse, monitoring quality in prod, controlling API spend, and modeling the economics of an AI feature.

8. Secure AI applications

Prompt injections, data leaks, RBAC, and agent security in your product – closing every key risk.

Course practice

The course is built around developing your own multi-agent AI system – from an n8n prototype to a production solution on LangGraph, with Observability, Evals, and cost control.

Every student picks one of four course tracks based on their professional domain and carries it through every stage – from system prompts to an agent shipped to production.

Stage 1: MCP and RAG

You write your own MCP servers in Python or TypeScript, stand up a local vector database (Qdrant), prepare a document corpus, and compute embeddings. You learn to tell when CAG is enough and when you actually need full-blown RAG.

Stage 2: Agents and architecture

You prototype 2–3 agents in n8n as a linear workflow, then port the logic to code on LangGraph – memory, state, looping, and autonomous routing between agents. You assemble a multi-agent scenario with the supervisor pattern.

Stage 3: The production wrapper

You add Evals on synthetic data, wire up tracing in Langfuse, set up spend alerting, and ship basic protection against prompt injections. You take agents to production with metrics, observability, and security.

Course assignments

  • 1
    Module 1. Your own MCP server

    You write a custom MCP server in Python or TypeScript for an internal database or script and plug it into Cursor / Windsurf.

  • 2
    Module 2. RAG on Qdrant

    You stand up a local Qdrant, prepare a document corpus, compute embeddings, and assemble a basic RAG with context caching.

  • 3
    Module 3. Agent prototype in n8n

    You prototype 2–3 agents from your course project as a linear workflow in n8n – with RAG and MCP tools already plugged in.

  • 4
    Module 4. Porting to LangGraph

    You port the agents from n8n into LangGraph code – adding loops, memory, and autonomous routing between steps and agents.

  • 5
    Module 5. Multi-agent scenario

    You implement a supervisor pattern or ReAct architecture for three agents in your course project – with split roles and shared context.

  • 6
    Module 6. Evals and tracing

    You generate a synthetic dataset, write LLM-as-a-Judge tests, and wire up Langfuse for tracing agent chains.

  • 7
    Module 7. FinOps and Security audit

    You set up cost-per-feature tracking, token limits, and budget alerts. You run a security audit of your agent – prompt injections, data leaks, RBAC – and close every issue you find.

Certificates

Your final certificate depends on how much practice you complete and on the defense of your course project:

  • "Audited" – the participant followed the course, attended the sessions, and worked through the materials without completing the practice.
  • "Completed" – at least 70% of homework done and a basic working setup in place: your own MCP, RAG, and an agent prototype in n8n.
  • "Completed with Distinction" – all homework done and the course project successfully defended: your own multi-agent system shipped to production with Observability, Evals, and cost control.

Prerequisites

Knowledge from L1 (or equivalent)

Confident use of an AI-IDE (Cursor / Windsurf), basic prompt engineering, and a clear sense of when to use code-focused models versus reasoning models. A seamless step up from the Level 1 course.

Programming

Python or TypeScript at a professional level – at least 2 years of commercial experience. Willingness to write code, not just configure ready-made tools.

Infrastructure

Hands-on experience with REST APIs, Docker, and databases. Willingness to run Qdrant locally and work from the CLI.

Learning process

Materials and ready-made code: A Git repository with MCP templates, RAG-pipeline scaffolds, and starter agent code – you launch them and grow them into your own course project.
Daily self-study: Theory, coding, and homework every day, with no rigid webinar schedule. Expected time commitment – 6–8 hours per week.
Sync sessions: Two meetings per week: course project reviews (architecture, code, product decisions), Q&A with AI engineers, and the final project defense.
Code review by mentors: A detailed review of your code by practicing AI engineers – from prompt quality to multi-agent system architecture.
Community: A private Telegram chat for participants and mentors – AI engineers with production experience – for questions, peer learning, and professional networking.

Format

Daily self-study

Theory, coding, and homework at your own pace. 6–8 hours per week, with all materials and repositories yours to keep forever.

Sync sessions

Two meetings per week: course project reviews (architecture, code, product decisions) and Q&A with AI engineers.

Code review and community

A detailed code review by mentors with production experience, plus a live Telegram chat with AI engineers.

Course project options
Multi-agent AI system

The end-to-end course project is a multi-agent system of three agents that you ship to production. You can pick one of four tracks based on your professional domain:

1. AI Editorial (SEO and content). A Writer gathers information and drafts the piece, a Fact-Checker verifies facts and Tone of Voice through RAG, and an SEO Specialist generates meta tags and final markup.
2. Smart Tech Support (Support Triage). A Classifier identifies the urgency and category of a ticket, a Tier-1 Support agent looks for a solution in RAG, and an Escalator hands complex cases off to an engineer through the task tracker.
3. Development Assistant (code review and docs). A Reviewer analyzes the git diff, a Tester writes unit tests for new functions, and a Documenter updates the README and docstrings.
4. Personal Knowledge Curator (Daily Digest). Once a day, a Collector pulls articles from RSS and Telegram, an Evaluator filters out the noise, and a Summarizer produces a digest in Notion or Telegram.

The track you choose is built up in layers across your homework:

Layer 1: Design and prompts. Defining the agents' roles, writing and tuning system prompts in a sandbox.
Layer 2: Prototyping in n8n. A linear workflow where agents pass data along a fixed chain.
Layer 3: Tools and RAG. Plugging in a local vector database (Qdrant) and basic tools (Tools / MCP).
Layer 4: Implementation on LangGraph. Porting to code, adding loops, memory, and autonomous routing between agents.
Layer 5: Observability and Evals. Wiring up tracing in Langfuse, evaluating quality, and preparing the final solution for the defense.

  • Practice: setting up spend alerting, plus a security audit of an AI agent with all findings closed out.

Why this course?

1. Production-ready, not Jupyter notebooks

The course teaches you to ship LLM solutions to real production – with metrics, monitoring, cost control, and protection against attacks – not leave them stuck at the notebook prototype stage.

Why this matters: This is the main gap between an AI enthusiast and an AI engineer. After this course, you can take on AI features with confidence that they'll actually reach users.

2. A seamless continuation of L1

The course picks up where L1 left off: from using ready-made tools to building your own. No filler – straight to the advanced material.

Why this matters: L1 students don't lose momentum and step right into serious development. You get the full picture – from your first .cursorrules all the way to a multi-agent system in production.

3. Multi-agent end to end

The full cycle: designing roles, prototyping in n8n, porting to LangGraph, multi-agent orchestration, and shipping to production.

Why this matters: Multi-agent systems are the leading technical trend of 2026. You walk away with your own working multi-agent system in your portfolio – not a "hello world," but a real-world solution.

4. The 2026 production stack

LangChain, LangGraph, Qdrant, Langfuse, n8n, Temporal – the real tools the industry uses to build AI solutions right now.

Why this matters: The course gives you the stack production teams actually use. Not training-wheel tools, but the industry kit – so you immediately fit in on any team working with LLMs.

5. Not just development, but the wrapper around it

Evals, Observability, FinOps, and Security – four blocks that most AI courses simply don't cover.

Why this matters: Most courses teach you "how to write an agent," but not "how to live with it in production." This one closes all four gaps – tests, monitoring, money, and security.

6. A course project tailored to your domain

Four tracks – AI Editorial, Smart Tech Support, a development assistant, or a Personal Knowledge Curator. You build the project that fits your work.

Why this matters: You're not writing throwaway code – you're solving a real scenario from your professional domain. The finished project can go straight to your team or into your actual workflow.

What our graduates say

Stories from graduates of the first run of Product AI Development – what they took away: confidence that you can build robust products on generative AI, an understanding of agents under the hood and the first chains in production.

Nikita Shumilin
“You can build fairly robust production products on generative AI”

Before the first course, AI-Driven Development, I had almost no experience working with agents. The course gave me an understanding of what kinds of agents there are, which ones to use and what tasks you can solve with them.

Before the first course, AI-Driven Development, I had almost no experience working with agents. The course gave me an understanding of what kinds of agents there are, which ones to use and what tasks you can solve with them. And something I didn’t expect at all: you can build products on all of this, and do it yourself, almost single-handedly.

The second course, Product AI Development, gave me more confidence: you can build fairly robust production products on generative AI, and it’s closer and simpler than it seems at first glance. I had experience building various systems, but I hadn’t built systems like these before – now I do. The topics are comprehensive, the homework is substantial, I had to dig into it, and I liked that. Most of all I liked the review of my AI work sessions: seeing from the outside, with an assessment, how I use AI is a very good tool, and I’ll keep using it.

“During the course I already managed to ship one chain to production”

I liked the course, there’s not much to criticize. It turned out deep in its materials: it’s hard to study everything to the end, but it covers the top-level understanding – what to try and where to go deeper.

I liked the course, there’s not much to criticize. It turned out deep in its materials: it’s hard to study everything to the end, but it covers the top-level understanding – what to try and where to go deeper. It’s all really cool: during the course I already managed to ship one chain to production.

What I value most is the format of working through questions and problems. You can study the theory afterwards in any convenient form – a recording, a summary, text. But you won’t get a discussion of real questions just anywhere: for that you need to find a group of people or a meetup.

Yauheni Yefimenka
“When you come and everything has already been structured for you, that’s worth a lot”

Technology is developing at tremendous speed, you can’t keep up with everything, and when you come and everything has already been structured for you, that’s worth a lot.

I take courses like this not to level up 100% as an engineer, but to broaden my perspective. Technology is developing at tremendous speed, you can’t keep up with everything, and when you come and everything has already been structured for you, that’s worth a lot. So I really enjoyed it. I didn’t understand everything 100%, but you can always go back to the materials and quickly figure out what to develop.

I really liked how Sergey ran the sessions: he went beyond the program, compared things with Google and other solutions, and after that a real interest in working with the technologies woke up. The course met my expectations 100%. The main idea I took away: thanks to AI, the very nature of business is changing, nobody relies on long-term versions anymore, so you need to build your own abstract solutions that cover as many providers as possible.

“I’m completely happy with both the direction of the course and its content”

I’m completely happy with both the direction of the course and its content. There wasn’t a single weak homework that makes you think “what’s the point of all this” – everything went into my piggy bank.

I’m completely happy with both the direction of the course and its content. There wasn’t a single weak homework that makes you think “what’s the point of all this” – everything went into my piggy bank. I especially liked the depth I saw at the final stages.

I liked that you can do part of a task at an intermediate level – a good compromise: you try, make mistakes a few times, correct yourself and see it through to the end. After all, we came here for practical experience – not only for hard skills, but also to strengthen our soft skills and practice them.

“The course is definitely worth the money – and more”

The course covers all the AI topics that matter right now. When you study on your own, it’s hard to focus on what really matters. Here, the theory is laid out step by step and in real depth.

The course covers all the AI topics that matter right now. When you study on your own, it’s hard to focus on what really matters. Here, the theory is laid out step by step and in real depth. I liked that you don’t have to look for other sources – everything is in one place. The course project is a great sandbox for trying out your skills.

Doing the homework was a pleasure. You could see how carefully everything had been thought through and how much effort had gone into it. The homework always came with clear instructions, and it was clear what result was expected. The amount of work and material is huge: it felt like the team had packed a year-long AI course into 2 months.

I think it’s a good foundation for getting certified later on. The course is definitely worth the money – and more. I’d take it again, with a different course project.
