Architect-Grade Java with LLMs

One day of coding, debating and shipping Java with Adam Bien (linkedin.com/in/adam-bien). Five years online. Now back at MUC, in person.

A small cohort, one full day, and a repository you keep.

This is an advanced, hands-on workshop on architect-grade, LLM-assisted Java development — using LLMs and agents to ship maintainable, well-tested Java without slipping into vibe coding.

What you'll learn

Agents, subagents, context, LLMs, MCP, tools, skills, agents and agent memory (...) basics / introduction

Developer / LLM synergy: who does what

Effective communication with domain experts and product owners

Bridging domain experts and Java implementation

Requirements clarification with stakeholders

From specs to working Java code

Spec-driven development for Java and Web Platform projects

LLM-native architectures, planning and design

Scaling LLM-driven development to large systems

The LLM impact on architectural principles:

• Rethinking DRY and DIE in the LLM era
• YAGNI and KISS in LLM-generated code
• Separation of Concerns with LLMs
• Maximal Cohesion, Minimal Coupling: why cohesion beats coupling in the context window
• Information hiding as a context-window strategy
• Reusability and modularization in LLM-first projects
• Do hexagonal architectures survive LLMs?
• Do we still need microservices?

Continuous improvement workflows for Java teams

Continuous review of generated Java code

Continuous compliance with architectural rules

Unit-, Integration- and System Testing with LLMs

Capturing architectural rules with Skills

Creating efficient AGENTS.md

Hyperproductivity without sacrificing maintainability
