About

Stephan Janssen is the founder of Devoxx, one of the world's leading developer conference series, now in its 19th edition in Belgium. His deep involvement in the developer community spans decades, bringing together thousands of technologists to explore cutting-edge innovations in software development.

Janssen focuses on the emerging era of AI Augmented Programming (AAP), particularly exploring how modern Java can be leveraged to build sophisticated AI systems. His work demonstrates practical approaches to integrating large language models into development workflows, including building custom RAG (Retrieval-Augmented Generation) systems that leverage 30+ LLMs for enhanced performance.

Through his presentations, he bridges the gap between traditional Java development and the latest AI capabilities, showing developers how to harness these technologies using familiar tools and languages. His conference talks span both technical deep-dives into AI-augmented programming and reflective perspectives on Devoxx's evolution, sharing insights from the conference's journey through past, present, and future challenges in the developer ecosystem.

Featured Talk

The Era of AAP: Ai Augmented Programming using Modern Java

As we enter the era of AI-Augmented Programming (AAP), developers stand at the threshold of a profound shift in software creation and maintenance. This talk delves into the emerging paradigm where Java and Large Language Models (LLMs) are leveraged to enhance and automate various stages of the development lifecycle. We'll explore how Java and LLMs are reshaping Integrated Development Environments (IDEs) and transforming developer workflows. The presentation will demo the integration of both local and remote LLMs, demonstrating their practical applications in coding assistance, debugging, and even generating entire projects from high-level prompts. We’ll also explore a new and exciting approach named Test-Driven Generation (TDG), which uses LLMs to align testing and code generation for a streamlined, quality-driven development process.
