Language Stacks and Gen AI
Python is the language of data science and dominant in AI research. However, it is not the language of enterprise apps, and there are good reasons for this. In this session, Rod will discuss when to use what language and stack for AI success in enterprise. He'll discuss the key adjacencies for success: LLMs, existing data and business logic, and how to choose what language, stack and framework for a particular problem.

A conference for Tech Leaders on the present and future of Artificial Intelligence
Includes a pass for the Devnexus Tech Leadership Track
8 practical sessions • Lunch Included • Networking Reception
We are past the point of asking if AI will change your business. The question is now how fast and how effectively you can wield it.
ADVANTAGE is the premier gathering for the technology leaders charged with navigating the AI revolution. Designed exclusively for CTOs, CIOs, VPs of Engineering, and Technical Leads, this isn't a conference about theoretical research—it’s a summit on practical implementation, governance, and scale.
In an era of overwhelming noise, ADVANTAGE provides the signal. We dissect the difference between flashy demos and production-ready architecture. We explore how to upskill your workforce, govern your data, and integrate LLMs into legacy systems without breaking them.
Join your peers to define the future of your stack, your product, and your organization.
