This event brings together developers to explore practical workflows, real-world use cases, and hands-on experiences using GitHub Copilot. Whether you are new to GitHub Copilot or already using it, this event will help you better understand how to apply AI-assisted coding techniques in everyday development. **Agenda** \- 4:30pm: Doors open\, Snacks\, and Networking \- 5:00pm: Welcome\, Community update \- 5:10pm\~5:40pm: Tech talk: GitHub Copilot overview \- 5:40pm\~6:40pm: Tech talk: GitHub Copilot in Practice \- 6:40pm\~7:30pm: Open discussion and closing **Tech talk: Mastering GitHub Copilot CLI** **Speaker:** Aymen Furter - Cloud & AI Solution Engineer, Microsoft **Abstract:** Learn to harness the power of agentic development by transitioning to autonomous, multi-step terminal workflows. This session focuses on mastering plan-based execution, repository-aware context, and integrating external data via the Model Context Protocol. **Tech talk: GitStop Using GitHub Copilot Like a Toy** **Speaker:** Emanuele Bartolesi - GitHub Tech Lead, Xebia **Abstract:** Hub Copilot is easy to love in a demo. Real projects are different. Production codebases come with legacy code, missing context, inconsistent patterns, unclear requirements, and delivery pressure. That is where GitHub Copilot either becomes a real advantage or just an expensive toy. This talk focuses on practical ways to use Copilot in real development workflows, going beyond autocomplete. Agent mode, skills, Copilot CLI, and better prompting can make a real difference when working in messy repositories and under real deadlines. Designed for developers and tech leads who want more than flashy demos, this session shares concrete tactics to get better output, reduce noise, and make Copilot genuinely useful in day-to-day software delivery. **Speakers/Topics:** Stay tuned as we are updating speakers and schedules. If you have a keen interest in speaking to our community, we invite you to submit topics for consideration: [Submit Topics](https://forms.gle/JkMt91CZRtoJBSFUA) **Venue:** Microsoft Schweiz GmbH The Circle 02, 8058 Zürich ZH **Sponsors:** We are actively seeking sponsors to support AI developers community.

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.

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!

**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.
