Agentic Engineering.

Practical, intense, bleeding edge Agentic Engineering training for Developers of any specialty. Taught by one of the most experienced trainers in Europe.

Introduction

Go from prompt & context engineering to autonomous agent orchestration in one day: learn context and prompt engineering, skills, subagents, spec-driven development, security best practices, and auto-improving agentic workflows. The gap between AI-native developers and the rest is widening fast.

Fundamentals

Core Concepts: Predictions, Tokens, Context Window, Compaction, System Prompt, Model vs Agent Harness
AI Pitfalls: Sycophancy, Hallucinations, Attention Dilution, Knowledge Cutoff, Premature Fixation (+solutions)

Context & Prompt Engineering

Evolving a Token-Efficient Project Memory
AI Context Sharing across repos, teams, and company
Skills and Custom Agents that self-improve
Few-shot Examples — prompt on the edge-cases (tell or ask)
Brainstorm Mode — surface unknown unknowns
One-Shot-Prompt Principle — deep steering AI decisions

Agentic Engineering

MCP explained + best-of: JIRA, CI, Chrome, DB, Figma, Telemetry, etc + your own
Feedback Loops for autonomous agents: tests, browser-screenshots, CI/CD-loop, and more
Multi-Agent Orchestration Patterns: handover, reviewer, orchestrator, advisor

Spec-Driven Development

Spec-Drive a vague brief with OpenSpec into a PRD, design, and [ ] tasks
Best way to review and adjust the generated spec & code

AI Guardrails & Security

Functional Guardrails with State-of-the-art Acceptance Tests
Code Quality Guardrails AI cannot circumvent
Architecture Guardrails & Summarization — APIs, C4 Model, sequence diagrams
Zero-Data-Retention, PII, GDPR, Secrets
Prompt Injection — contest: hack a chat bot
Supply-Chain Attacks via Skill, MCP, Slop-Squatting
Agent Isolation Strategies: auto-mode, sandbox mode, Docker-isolation, microVM

FAQ

Who is this course for?

The course is designed for engineers of any specialty (Backend, Frontend, Mobile, QA Automation, Data Scientists, DevOps), architects, technical leads and freelancers looking to learn how to build robust, high quality software with AI.

What are the prerequisites for this course?

Prior experience with ChatGPT, GitHub Copilot or (ideally) a CLI tool like Claude Code or Codex.

How is the learning process?

The course is a mix of slides, demos, group discussions, and hands-on exercises.

What tech will be used for demos/exercises?

Claude Code on a full-stack application but the lessons will be applicable to any other AI harness (Codex, Copilot) and tech stack (Py, TS, C#, Kt, …).

Do I need to prepare for this course?

Yes, if you want to get the most of it.
📺 You will get some prep-materials covering the basics.
🛠️ For the hands-on exercises, you will need Claude Code installed (a Pro subscription is enough). You will receive setup instructions ~1 week in advance.

Isn't a single day too little time?

Indeed, I give an extended version of this workshop to companies over 2 full days. However, this single training day assumes you had prior contact with AI-assisted engineering, and are willing to walk through a couple of hours of prep work that I will provide you in advance. It is nevertheless possible that agentic.how workshop will be expanded to 2 days in the future.

Will I receive a certificate?

Yes, you’ll receive a digitally verifiable certificate of accomplishment.

Is the course recorded?

No.
But what you'll get will be far better⭐️ – all slides (packed with links) and a state-of-the-art AI summary of the training transcription, that you can then browse and search.

What is the timeframe of the workshop?

⏱️ 9:00am – 5:00pm CET (Central European Time)
⏱️ 9:00am – 5:00pm GMT+2 (in your current time)

How can I keep learning after the course?

⭐️ I will answer your emails after the training, and and may occasionally offer free follow-up hours for 1:1 coaching or consultancy.
⭐️ Each participant will learn how to build their own ‘Personal Tutor’ ChatBot that will help them sink into the contents covered over the following weeks.
⭐️ You will receive a list of books, blogs, and videos for further study.
⭐️ After the course, you'll remain connected with other alumni via group chat.
