Financial Engineering

**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.

That they’re “for later.”That you can’t touch them. That real estate and retirement money don’t mix. They’re wrong. This meetup is about how investors use **Self-Directed IRAs and Solo 401(k)s** to put retirement capital to work…**buying real estate, funding deals, and even raising private money** (the right way). ### **Featured Guest Speaker: Amanda Holbrook** We’re excited to welcome **Amanda Holbrook of Specialized Trust Company** to break this down clearly and practically…so you understand what’s allowed, how it works, and what to avoid. ### **What You’ll Learn** Amanda will walk through: **Flip inside a Self-Directed IRA or Solo-401(k)** * How to structure the deal correctly * How expenses must be handled * When UBIT may apply **Wholesale within a retirement account** * How assignments work * What type of income it creates **Use OPM (Other People’s Money) to scale** * How investors raise private money from Self-Directed IRAs * How to structure notes properly * How to fund deals inside **and** outside your own retirement account ### **The Core Idea** There is a lot of capital sitting in retirement accounts. This session shows you how real estate investors unlock it **without guessing, winging it, or accidentally creating a compliance mess.** ### **Who This Event Is For** * Investors flipping or wholesaling who want to understand self-directed rules * Anyone raising private money (or wanting more capital sources) * People with retirement funds who want them working harder than stocks/mutual funds ### **Event Details** **Location:** Ohio Brewing Company – 421 E 2nd Ave, Columbus, OH 43201 **Date & Time:** Thursday, March 26th, 6–8 PM *(Doors open at 5:30)* **Cost:** Free *(Seats are limited — RSVP required)* **Food:** Free food included **FREE meetup.

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.
