We’re serious about helping you succeed in real estate. That means not just teaching you—but putting you in the room with the people who help you get deals done. Every deal depends on people. The agent or wholesaler. The lender. The contractor. The title company. The insurance agent. The problem is that most investors meet those people slowly. This event fixes that. One room full of: • Lenders • Contractors • Title companies • Insurance providers • Property managers • And active local investors A place where you can: • Build your team • Find funding • Solve real problems • Make connections that lead to deals If you’re serious about real estate, this is a smart room to be in. Members and non-members at any level of knowledge and experience are welcome. This event is free.

Whether you've never done improv before, or you've done it for so long you knew Del Close on a personal level, or anywhere in between, come join us! Swing by *Gresso's* for the **Columbus Improv Comedy Meetup** for some fun and games! The idea behind improv is to create entire scenes from scratch based on a suggestion from the audience. This can be done in game form, like *Whose Line Is It Anyway*, *ComedySportz*, or *Wild 'n Out*; it could also be done to tell stories, like *Middleditch and Schwartz*. Our meetup, which is central Ohio's longest running (and free!) weekly comedy event, brings the games (and occasionally different forms) for you to play in a safe, supportive, and compassionate environment. Not only is it a lot of fun, but you get to work on thinking faster on your feet, plus it's an excellent way to meet new people and make friendships that'll last a lifetime! Ask yourself if you want to join the **Columbus Improv Comedy Meetup**, and say "Yes, And" that you'll have fun!

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
