The Evolution of Design Patterns in the Age of AI by Miro Wengner [16.03.2026]

The remarkable growth of artificial intelligence, particularly Large Language Models (LLMs) and AI-assisted coding, in recent years has introduced new challenges to software development. While LLMs can generate valuable outputs and code solutions, human oversight has become essential to prevent codebase deterioration, unexpected behaviors, and security vulnerabilities. Although the Gang of Four made significant contributions by identifying common software design challenges that businesses faced in the past, the technology landscape has evolved considerably. The widespread adoption of agentic AI systems has fundamentally changed how we approach software development, necessitating a fresh perspective on established practices. This evolution leads to an important conclusion: traditional design patterns and anti-patterns must be reconsidered in light of AI-driven development practices. This presentation will demonstrate how to enhance delivery flow and strengthen fast-feedback loops while identifying bottlenecks and eliminating obstacles from codebases. During the presentation, we will examine the characteristics of several anti-patterns that have emerged in AI-assisted development and explore how to transform them into effective design patterns that meet modern business requirements. --- About the speaker Miro is a distinguished engineer, AI scientist, architect, and team lead with a deep passion for resilient distributed systems and software craftsmanship.
