Master Agentic Engineering in One Day
Go from prompt engineering to autonomous agent orchestration in one intensive day. Learn hooks, skills, subagents, spec-driven development, and agent loops — using Claude Code with your team's actual codebase.

What You'll Master
Practical skills you'll apply immediately after the workshop
LLM Fundamentals
From transformer architecture to the ReAct pattern. Understand prompt engineering, temperature, context windows, RAG, embeddings, and how the MCP agentic loop actually works under the hood.
Claude Code Ecosystem
Master the paradigm shift from autocomplete to agentic execution. Compare terminal-first tools (Claude Code, Codex CLI, Gemini CLI, Kimi, Kiro), explore sandboxing, GitHub Actions integration, and the full unified architecture across CLI, Desktop, and Mobile.
Hooks
Transform AI suggestions into deterministic, enforced workflows. Build PreToolUse, PostToolUse, and UserPromptSubmit hooks that auto-format code, enforce policies, and guard sensitive operations — all wired through stdin/stdout exit codes.
Commands & Skills
Go beyond "AI writes code" to "AI runs my workflow." Build custom slash commands for daily tasks, then supercharge them as Skills with enhanced context, lazy loading, YAML control, and reusable persistence — shareable across your entire team.
Subagents & Orchestration
Delegate complex tasks to specialist agents — Debugger, Test Writer, Security Auditor, System Architect. Learn orchestration patterns, least-privilege tool scoping, isolated context windows, and parallel execution for real-world codebases.
PSI, MCP & LSP Integration
Connect Claude Code to your IDE at a semantic level. Use JetBrains PSI for AST-aware refactoring, symbol resolution, and type-safe analysis. Understand when to choose MCP over LSP and how to build IDE-native agentic pipelines.
Spec-Driven Development
Escape vibe coding chaos with markdown-as-source-of-truth. Learn the Spec → Plan → Implement flow, use Backlog.md for task management, avoid common pitfalls, and build quality gates that keep AI output production-ready.
Agent Loops & Automation
Build autonomous Act → Evaluate → Persist → Repeat cycles. Scale with Git Worktrees for parallel workspaces, run isolated Docker sandboxes, and operationalize loops as production runner processes with PRD-driven dashboards.
Your Codebase, Your Rules
I sign an NDA and train on your team's actual codebase. Every exercise uses your real stack, real challenges, and real goals — so developers walk away applying what they learned from day one.
Master AI Inside Your JetBrains IDE
A full-day deep dive into DevoxxGenie — taught by its creator
DevoxxGenie Architecture & Setup
Plugin architecture, LLM provider configuration (OpenAI, Anthropic, Mistral, Groq, Gemini, Ollama, LM Studio, GPT4All), multi-provider setup, and bring-your-own-key model management.
Agent Mode & Spec-Driven Development
Autonomous codebase exploration and modification with built-in tools (read/write/edit/search files, run commands). Safety approvals, Backlog.md integration, and structured specs with acceptance criteria.
Parallel Sub-Agents
Concurrent investigation across multiple project aspects with up to 10 agent slots. Per-agent model/provider override, isolated context and tool call budgets, and cost optimization strategies.
MCP & Plugin Integrations
MCP Marketplace for browsing and installing servers, real-time MCP debugging panel, Plugin Integration API for third-party IntelliJ plugins, and CLI Runners (Claude Code, Copilot, Codex, Gemini CLI).
Security & Code Quality
Gitleaks (secret detection), OpenGrep (SAST), Trivy (CVE scanning), SpotBugs integration for AI-assisted bug finding, SonarQube integration for code quality analysis, and automated backlog task creation per finding.
Inline Completion & Advanced Workflows
FIM model support via Ollama/LM Studio, drag & drop image context for multimodal LLMs, batch task execution, and team collaboration patterns.

What developers said about Stephan's presentations
Stephan has an infectious enthusiasm and a great way of summarizing the interesting topics in tech today.
Super energetic and enthusiastic introduction. Always brought with passion and a healthy portion of humour.
Great introduction! I really enjoyed how you were showcasing the rise of agents by doing the vibe coding experiment.
You hit exactly the right notes on what I experienced with agent based coding. Love it!
Always a pleasure to see you on stage. Sharing all your energy and good vibes about our work.
Awesome and motivating introduction as always. As a first timer, felt welcome!
