Event Driven AI Orchestrator [foobar.i/o #10]
Event Driven AI Orchestrator [foobar.i/o #10]
We are rolling into the **10th** iteration of foobar.i/o with **"Event Driven AI Orchestrator"** **The case:** **AI agents** are powerful but unpredictable. The real challenge isn't making them smarter, it's keeping them under control. In this session, [Eric Johnson](https://www.linkedin.com/in/singledigit/) builds an event-driven AI orchestrator using serverless on **AWS**, where deterministic infrastructure orchestrates non-deterministic AI agents. You'll see how *EventBridge,* *Step Functions*, and *Lambda* work together to coordinate agents that can reason freely while the system enforces guardrails, retries, and sequencing. **The result**: AI that's useful without being dangerous. This is a live-build **session,** expect **working code,** **real demos,** and **practical patterns** you can take home. Who would really want to miss that? Join us Tuesday, **May 12** 𝗮𝘁 **6:30** 𝗽𝗺 for the pre-summer edition of [foobar io Greece](https://www.linkedin.com/company/foobar-io-greece/) meetup! You will find us at **Michalakopoulou 80**,**Athens** (1st floor) hosted by [XM](https://www.linkedin.com/company/xm-global/) (again)! **Bio**: **Eric Johnson** is a **Principal Developer Advocate** at Amazon Web Services and a father of five who believes technology should be fun. He specializes in serverless architectures and has built a reputation for making complex technical concepts genuinely understandable. A keynote speaker at conferences worldwide, Eric is most at home on stage, whether he's breaking down event-driven design for seasoned architects or encouraging students writing their first lines of code. He brings humor and energy to everything he does, because he's convinced that if you're not enjoying the work, you're doing it wrong.

Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
Building Scalable Customer Identity Resolution Pipelines on AWS Using AI
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!

CBusData - Practical AI for Power BI Developers
CBusData - Practical AI for Power BI Developers
Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
Data & Analytics Wednesday - Mapping and Dashboards
Data & Analytics Wednesday - Mapping and Dashboards
**Total Eclipse of the Chart: School Redistricting Dashboards** In this presentation, we will explore the utilization of maps, sets, and SQL within a Tableau dashboard to help provide “what-if” analyses generated through the use of a mapped dashboard, providing different scenarios and the potential implications of these. While in this use case we are focused on a large school district, the concepts of utilizing existing data to explore the future impacts of modifying different geographic boundaries can be useful to many industries, balancing the mix of maps with visual analytics. **About Our Speaker** Robert Kramer is the Data Systems and State Reporting Coordinator at South Western City Schools in Grove City. He has worked there for 17 years, serving previously in the roles of Data Analyst, Programmer, and Operations Coordinator. Prior to working at South Western, he worked as a Systems Engineer at Pinnacle Data Systems in Groveport. He graduated in 2005 from The University of Toledo with his Bachelor’s in Computer Science and Engineering, and a minor in Mathematics. Robert resides in Obetz with his wife, and their 15 and 12 year-old daughters. He was also just elected to his 3rd four-year term on the Obetz City Council. Thanks to our 2026 sponsors: [Clarivoy](https://www.clarivoy.com), [What Box Consulting Group](https://www.whatboxconsultinggroup.com), [Conductrics](https://www.conductrics.com), and [Piwik PRO](https://piwik.pro) More info at [cbusdaw.com](https://cbusdaw.com)

No slides required — just a welcoming space to exchange ideas and keep the local AI conversation moving. If you’d like to take the stage, message \*\*Chris (the organizer)\*\*with a **title and short description** of what you’d like to share. Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.

LLM Showdown: ChatGPT vs Claude vs Gemini vs Local Models
LLM Showdown: ChatGPT vs Claude vs Gemini vs Local Models
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.
