**First meetup of the Columbus AI Engineering group.** We’ll kick things off with a practical, beginner-friendly discussion on: **How LLMs like ChatGPT actually work — and how to build real applications with them.** We’ll cover: * what’s actually happening under the hood (at a high level) * why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.) * how people are building real systems with them today * where things break in practice This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A. Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join. No slides, no fluff — just real conversation about real systems. We’ll hang out afterward and get to know each other.

**Connected Westerville Night of Networking** *April Edition: The Introduction Economy* You've been to the networking events. You've done the small talk. Collected the cards. Forgotten the names. And walked out feeling like you just wasted two hours of your life. The problem isn't you. It's the format. Most networking events put you in a room and tell you to figure it out. So everyone defaults to elevator pitches and business talk, and nothing real gets built. Here's the truth about networking that most people miss: Your network isn't just who you know. It's who thinks of you when they're talking to someone else. *That's* The Introduction Economy. And it only works when relationships are real. There's a reason people who come once keep coming back. It starts with seven minutes that feel nothing like networking. Then we open it up. Free networking. More conversations. More momentum. This is a room full of corporate professionals, entrepreneurs, business owners, creatives, and career builders in the Westerville and Columbus area. The mix is the magic. You might never do business with everyone you meet tonight. But someone in this room will think of *you.* **By name**. So, the next time someone needs exactly what you do, you get the recommendation. **April 14th. RSVP now.** **When:** Tuesday\, April 14th \| 6:15 PM \-\- 8:00 PM **Where:** Vineyard Community Center \| 6000 Cooper Rd\, Westerville\, OH 43081

Our monthly PHP meetup. A virtual shindig courtesy of Zoom. Check back here for the details around 6:15 pm

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.
