We share tools and frameworks used (as well as tradeoffs and alternatives), and discuss methods such as LLM-as-Judge, rules-based evaluations, ML metrics used, as well as selection tradeoffs. **Bio:** Susan Shu Chang is a Principal Data Scientist at Elastic, where she leads work on production-grade machine learning, including generative AI and agentic workflows. She is also an internationally recognized speaker, O’Reilly author, and keynote presenter at major global technical conferences. **My Elasticsearch Journey – Working in Different Industries** This talk explores Yasir Zaidi’s hands-on experience using Elastic products to deliver strategic solutions across banking, insurance, and telecommunications. Through real-world examples, the session will cover how Elasticsearch and the broader Elastic Stack have been used for search architecture, security, SIEM, and observability, along with some of the newer and more exciting projects now being built with Elastic. The talk will also highlight recent Elasticsearch features and innovations, and how they are opening up new possibilities for modern enterprise use cases. **Bio:** Yasir Zaidi is the Owner of ZD Inc.

**This is a ticketed event. Please register at [this link](https://luma.com/n5d2q50u).** ​The Platonic Representation Hypothesis (Huh et al., 2024) proposes that neural networks are converging toward a shared statistical model of objective reality, offering a Platonic explanation for the growing representational similarity observed across models of different architectures, datasets, and modalities. In this talk, Robert Adragna argues that such convergence is computationally intractable in practice. Truly representing reality would require models to recognize the same real-world concept across all its possible appearances — a form of robustness that theoretical and empirical work suggests is infeasible to achieve at scale. He proposes an alternative account: representational convergence reflects shared structural assumptions embedded in training data, not the discovery of objective reality. ​​​**Event Schedule** 6:00 to 6:30 - Food and introductions 6:30 to 7:30 - Presentation and Q&A 7:30 to 9:00 - Open Discussions ​​​​​​If you can't make it in person, feel free to join the live stream starting at 6:30 pm, via [this link](https://www.youtube.com/@Trajectory-Labs/live).

Struggling with motivation and focus as you hammer away on your manuscript at home? Want to join a community of writers as we embrace the joys and pains (mostly pains) of writing together? Bring your laptop, pen & paper, old-school typewriter, or futuristic writing gadget, and join an enthusiastic community of science fiction and fantasy writers as we work on our current projects in the same space. The format will be similar to our online writing sprints: 30-minute blocks of focused, quiet writing time (the sprints), interspersed with breaks where we can chat, ask questions, and share our writing experiences.

Let’s do some coding together at a cafe! No more working alone in the weekend. Here, we write code together. And I mean together together. Not occupying-the-same-space-but-separate together. Here’s how it works: Jennifer brings her mobile app project, tells everyone that it is like Pinterest for recipes and she’d like to work on the nav bar. Paul and Chloe think Jennifer's project is fascinating, and they join the group. They gather around Jennifer’s laptop and work on the nav bar for 2 hours. Jennifer is the one typing out the code while Paul and Chloe research, brainstorm, and offer suggestions. If you’re feeling stuck on your own project or need a motivation boost, bring it to mob programming! Want to learn by watching how others code and solve problems? Join someone else’s project at this event! Oh and we love your half-done projects that you are a bit embarrassed to share. Absolutely bring those to the event! **Discord**: We use Discord to share screen & code snippets during the event. Also feel free to share your projects here before the event! https://discord.gg/xwjDdVSw3E **Event policy**: * We have 0 tolerance for harassment. * We don’t allow the projects that are not meant to be shared in public such as school assignments, interview tasks, or trade secrets. * The goal is to write code. We discourage you from pitching business ideas here, doing code reviews, or spending the whole event on planning what to do. * Please buy a drink, and tip the barista well.

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!

**Abstract:** This is a practical playbook for building a production-grade data lakehouse. It walks through foundational principles — naming conventions, least-privilege access, automated CI/CD testing — before diving into medallion architecture. Furthermore, metadata-driven design patterns show how configuration tables and dynamic notebook orchestration eliminates hard-coded pipelines. The deck covers star schema modeling, guidance on choosing between Spark, Pandas, and SQL, and data quality enforcement using DQX with YAML data contracts. Finally, we dive into security best practices and performance optimizations. **Host:** Justin Shea, Mehdi Jeddi, Erik Pak, and Sou-Cheng Choi **Talk Format:** This is a hybrid event.
