Instead of starting from scratch, he treats codebases like excavation sites, applying data-driven analysis to reveal how old code actually works. He uses large language models and open-source tools to map out complex legacy architecture. By combining modern AI with software archeology, Markus gives developers the context they need to navigate missing documentation and safely update older frameworks. ## Past Sessions ### World Congress 2025 路 July 9, 2025 Berlin, Germany - [Getting to Know Your Legacy (System) with AI-Driven Software Archeology](https://www.wearedevelopers.com/videos/1437-getting-to-know-your-legacy-system-with-ai-driven-software-archeology) 路 30 min 路 馃帴 Watch recording ## Videos - [Getting to Know Your Legacy (System) with AI-Driven Software Archeology](https://www.wearedevelopers.com/videos/1437-getting-to-know-your-legacy-system-with-ai-driven-software-archeology) 路 Markus Harrer - [Wardley Maps for Software Developers](https://www.wearedevelopers.com/videos/665-wardley-maps-for-software-developers) 路 Markus Harrer - [Data Science on Software Data](https://www.wearedevelopers.com/videos/162-data-science-on-software-data) 路 Markus Harrer ## Links - [X](https://x.com/markus_harrer) - [LinkedIn](https://www.linkedin.com/in/markus-harrer/)
