The Tech Blog Writer Podcast - Inspired Tech Startup Stories & Interviews With Tech Leaders, Entrepreneurs And Innovators

In this episode of Tech Talks Daily, I explore the cutting-edge intersection of AI and software development with Justine Gehring, an AI researcher at Moderne and the author of AI for Mass-Scale Code Refactoring and Analysis. Justine shares her insights into how AI is addressing one of the most complex challenges in the industry: large-scale code migrations and updates across enterprise environments. While AI tools like GitHub Copilot and ChatGPT have excelled at assisting individual developers with writing and optimizing code, Justine explains how large-scale code refactoring requires an entirely different approach. At this level, AI must account for enterprise-wide complexity, maintain reliability, and ensure security across thousands of repositories. She also dives into Moderne’s use of open-source frameworks like OpenRewrite, which enable deterministic, verifiable code changes and combine machine learning for targeted tasks. We also discuss how this transformative use of AI is reshaping collaboration betwe
