In our second episode of AIMUG Builders, we sat down with Jeff Linwood to dig into how LLMs can actually improve the software development lifecycle—not just generate snippets.

Jeff has 25+ years of development experience and is leading work on ZapCircle, a TypeScript + LangChain framework designed for real-world teams. This wasn't a theoretical chat—we went straight into what works, what breaks, and how to bring LLMs into existing systems.

🔑 Key Takeaways​

  • ZapCircle Framework (TS + LangChain) A practical dev framework that makes LangChain fit naturally into TypeScript apps.

  • Behavior-Driven Development (BDD) with LLM prompts Using LLMs to turn plain-language scenarios into testable behaviors, making teams faster without skipping rigor.

  • Human-in-the-loop Code Review Pipelines Why code review isn't going away—and how to build LLM assistive review flows that keep trust intact.

  • Integration Patterns Hard lessons from trying to plug LLMs into existing stacks—where they accelerate teams, and where they can grind things to a halt.

Why It Matters​

So much LLM content online is toy demos. AIMUG Builders is about real engineering practices—things you can put into production tomorrow. If you're building with LangChain, LangGraph, or integrating LLMs into your stack, you'll find signal here.
