Data Analytics

Hello PyData People! We are excited to announce our next event of 2026! This time, we will be hosted at Generali Italia’s Torre Generali in Milan for an evening dedicated to open data, data platform orchestration, and scalable data engineering. 📅 When: Thursday, May 19th, 2026 – 18:30–21:00 📍 Where: Torre Generali Italia, Milan ⚠️ Important: Spots are limited. Please keep your RSVP updated to allow others to participate if you can no longer attend. *** **🕒 Agenda** 18:30 – Doors open & check-in 19:00 – Talk 1: Democratizing Data: A deep dive into Eurostat Open Database – Simona Mazzarino 19:45 – Talk 2: Scaling Data Mesh Orchestration with Dagster: Platform-Driven DAGs without Platform Friction – Marco Santoni and Andrea Romeo 20:30 – Networking & Social Dinner *** **🎤 The Talks** **1️⃣ Democratizing Data: A deep dive into Eurostat Open Database** Speaker: Simona Mazzarino (Data Scientist @ Clearbox AI) In this talk, we explore how to turn open data into actionable insights. You will learn how to navigate Eurostat, the EU’s vast statistical database, and use Python tools to fetch and process data for research, AI, and real-world analysis. We will look at how to discover relevant datasets, work with Eurostat’s interface and APIs, and integrate public statistics into your workflows for visualizations, dashboards, and models. A guiding example will be the analysis of migration flows across European countries, from data discovery to a usable dataset for analytics or machine learning. About the Speaker: Simona Mazzarino is a Data Scientist at Clearbox AI. With a background in linguistics, semiotics, and artificial intelligence, she specializes in language technologies. She is an active volunteer in the Python Torino community, where she helps connect people interested in Python applications, and she also volunteers for PyCon Italia. *** **2️⃣ Scaling Data Mesh Orchestration with Dagster: Platform-Driven DAGs without Platform Friction** Speakers: Andrea Romeo, Platform Engineer @ TeamSystem Data Mesh promises scalability and autonomy, but orchestration often becomes the hidden bottleneck: as data products grow, cross-domain dependencies explode, DAGs become fragile, and upstream teams are forced to react to every new consumer. In this talk, we present a platform-designed orchestration solution built on top of Dagster that enables company-wide orchestration without coupling data products together. Instead of requiring data engineers to manually define DAGs or modify upstream pipelines, each data product simply declares its dependencies on upstream output ports. From these declarations, the platform automatically builds and maintains the global DAG behind the scenes, ensuring that upstream data products remain unaffected by new consumers, orchestration scales as the number of data products grows, and platform standards are enforced without slowing down teams. We’ll walk through: * the orchestration challenges we faced when adopting data mesh at scale * how Dagster was extended and shaped into a platform abstraction, not exposed directly to product teams * the Python-based design patterns used to dynamically generate and evolve DAGs * the resulting developer experience for data engineers building data products This session is a practical, production-tested story of how Python and Dagster can be used to enable scalable orchestration in a real data mesh implementation — without turning the platform team into a bottleneck. About the Speakers: Andrea Romeo is a Platform Engineer at TeamSystem, where he focuses on building and evolving the technical foundation behind data infrastructure. He works closely with development and data teams to design scalable, resilient platforms that support data-driven products and services, with a strong focus on backend, cloud technologies, and developer experience. *** See you there!

Sono proprietario di un bar e dispongo di un tavolo da biliardo semi-professionale. Sto creando un gruppo WhatsApp di giocatori amatoriali di biliardo americano pool/carambola, per la maggior parte debuttanti. Cerco persone disposte a unirsi al gruppo per giocare e divertirsi nel tempo libero, il pomeriggio oppure la sera in ogni giorno. Per stimolare l'impegno di ogni giocatore, abbiamo pattuito che il vincitore di ogni "mini-torneo" organizzato nei vari giorni giochi gratis e non paghi la tariffa di tempo per il periodo di gioco (un'ora di gioco costa 10€, ma viene di volta in volta frazionata in base al periodo di gioco effettivo). Il locale si trova in zona nord di Milano, stazione Greco-Pirelli, università Bicocca. Chiunque dovesse essere davvero interessato a partecipare e unirsi al mio gruppo, non esiti a contattarmi. Cerco persone serie e disposte solamente a divertirsi, senza puntare mazzette grazie mille. Antonio

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.

Free parking will be available at the front and back sides of the Switchbox Office.

**Welcome to Drunken Philosophy** a casual, curious social discussion **Optional topic for this meetup: What's up with all the AI hate?** A recent survey found that 74% of Americans have a negative view of AI, and I want to know why. Come out and debate whether AI is good or bad. My hot take: a labor-saving tool that could potentially help cure cancer gets called dangerous because it might raise unemployment or cause a speculative investment bubble, that tells you a lot more about capitalism and the economic system we live under than it does about the tool itself. As a computer programmer, I think AI is a wonderful tool that has increased my productivity by at least an order of magnitude. I'd go so far as to say Claude Code is the best tool I have ever used. Debate me and name a better one. Is AI potentially dangerous? Yes, but so are a lot of tools. Chainsaws. Steam engines (early ones would occasionally explode and kill everyone in the room). Do you think cavemen sat around debating whether fire could be used as a weapon or for self-harm, and decided not to discover it? I have two friends who hate AI for opposite reasons: one thinks it's a fad and not useful, and the other thinks it's going to take over everything and cause human extinction. Come out tonight, have a friendly debate, and make some friends. No lectures. Friendly crowd. Drop in for one drink and stay if it's fun.
