Costruire una data platform in contesti enterprise è spesso una battaglia quotidiana. Dati duplicati, pipeline fragili e trasformazioni poco tracciabili. Processi di sviluppo sul dato difficili da testare, versionare e rilasciare in sicurezza. Cataloghi presenti ma scollegati dai flussi reali, governance dichiarata ma non operativa. Piattaforme che crescono nel tempo, aumentando complessità e perdita di controllo. Il paradigma Data Lakehouse open source promette ordine, scalabilità e flessibilità — ma come si traduce davvero in produzione, quando entrano in gioco: \- requisiti enterprise \- qualità del dato \- testing \- CI/CD \- governance reale \- responsabilità e ownership? 👉 Questo meetup nasce per rispondere a questa domanda, partendo da un caso d’uso reale, sviluppato e messo in produzione. **Agenda** * 18:30 – 18:45 **Benvenuto e Networking** * 18:45 – 19: 40 **Lakehouse Open Source in produzione: architettura, governance e developer experience in un caso reale** * 19:40 – 20:00 **Community Slot** (Proponi il tuo talk) * 20:00 – 20:30 **Q&A e Saluti** Registrati subito al meetup per ricevere tutti gli aggiornamenti sull'agenda. **Lakehouse Open Source in produzione: architettura, governance e developer experience in un caso reale** Il paradigma del data lakehouse open source rappresenta oggi una scelta strategica anche in contesti enterprise complessi. In questo meetup presenteremo uno use case reale, mostrando come sia possibile costruire una data platform moderna basata su tecnologie open source. Il talk si concentrerà sull’adozione di pratiche data-driven e developer-oriented, evidenziando il ruolo di **dbt** nel garantire replicabilità, qualità del dato, testing e integrazione con pipeline CI/CD. A completare il quadro, affronteremo i temi di data governance e data discovery attraverso **DataHub** e **OpenMetadata**, illustrando come un data catalog centralizzato abiliti tracciabilità, ownership e governance nel dato. Un percorso pratico per portare i data lakehouse open source verso una vera data platform moderna che possa rispondere a esigenze enterprise reali. **Lorenzo Pasco - Data Engineer @Seacom Società Benefit:** Laureato in Artificial Intelligence and Data Engineering a Pisa, fin da giovane, ho alimentato la mia passione per l’informatica e i videogiochi, unendo la tecnologia alla mia vita quotidiana. Al di là del digitale, il mio cuore batte per lo sport, in particolare il calcio, e sperimento la creatività in cucina. **Se stai cercando di capire come rendere i Data Lakehouse davvero “enterprise-ready”, questo meetup è l’occasione per confrontarti su un’esperienza reale, fatta di architettura, codice, governance e persone.** Come sempre, ci sarà ampio spazio per il confronto, le domande e le discussioni aperte

**Hello PyData People!** We are excited to announce our **second event of 2026**! This time, we will be hosted at **iliad Italia**'s headquarters in Milan for an evening dedicated to AI at scale—ranging from Foundation Models for credit risk to sovereign and open-source data architectures. 📅 **When:** Wednesday, February 18, 2026 📍 **Where:** iliad Italia, Viale Francesco Restelli, 1A, 20124 · Milano **⚠️ 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:** Open Source & Sovereign Architecture – Riccardo Lorenzon * **19:45:** 🎤 **Talk 2:** Klarna’s Foundation Model – Valeria Verzi, Sudhakar Periyasamy, Goran Dizdarevic * **20:30:** 🍕 **Networking & Aperitivo** offered by Iliad! *** ## 🎤 The Talks ## 1️⃣An Open Source and Sovereign Architecture for Data, ML and AI **Speaker:** Riccardo Lorenzon (Head of Data @ iliad Italia) Iliad Group invests billions in sovereign AI ecosystems, open-source tech, and low-carbon data centers to reduce reliance on non-European providers and bolster Europe's technological autonomy. True to Iliad Group's 'make-over-buy' culture of full control, iliad Italia is building a data architecture in a hybrid on-prem and Scaleway (Iliad Group cloud) setup, combining open-source tech and managed services. This powers data management, self-service analytics, and ML/AI use cases for our 12m+ user base and 1000+ employees. During this speech, we will guide you through the tech journeys we have built and are building. **About the Speaker:** Riccardo Lorenzon serves as Head of Data at iliad Italia, where he works on evolving the data function into a modern setup covering the full data value chain from sources to business decisions. He previously led data teams at Vedrai, an AI startup, and Whirlpool EMEA, handling projects in analytics, machine learning, and cloud platforms across areas like consumer service, supply chain, and sales. With a Master’s in Mathematical Engineering from Politecnico di Milano and studies at ETH Zürich, he combines a hands-on approach to delivery with a strong focus on strategic value for the business. *** ## 2️⃣ Building the Klarna Foundation Model: A Unified Transformer for Customer Behavior Modeling at Scale **Speaker:** Valeria Verzi (Principal Data Scientist @ Klarna), Sudhakar Periyasamy, Goran Dizdarevic In this session, we introduce Klarna’s Foundation Model (KFM): a lightweight Transformer trained on more than 130 million customer events to learn a unified representation of customer behavior. Rather than building separate, task-specific models, KFM operates as a common sequence-modeling backbone that encodes behavioral patterns across different touchpoints of a customer’s interaction history with Klarna. We will walk through the technical design of the system, including event tokenization, sequence construction, and Transformer architecture, as well as how the learned embeddings are exposed as a shared layer for multiple downstream use cases. Attendees will gain a concrete understanding of how foundation models can be applied to behavioral sequence data in fintech, and how a single model can serve as a reusable, extensible representation layer across heterogeneous modeling tasks. **About the Speaker:** Valeria Verzi is a Principal AI Scientist at Klarna, where she leads the development of next-generation models, from foundation models to advanced deep learning or agentic systems. She has nearly a decade of experience applying machine learning to high-stakes decisioning across fintech and insurance. Before her current role, Valeria served as Klarna’s Head of Data Science for Fraud Prevention. Prior to Klarna, she held senior data science roles at Generali and NTT Data. Valeria holds a Master’s degree in Computer Science Engineering from Politecnico di Milano. *** See you there! 🚀 *The PyData Milano Team*

**(7:00 PM)** 🔹**Please fill in your details to confirm your attendance.** https://forms.gle/GmCTgY1SDqeHS6cG9 **Talk: The power of color in personal branding** How to build a memorable color identity Color is not an aesthetic choice. It's a strategic lever. Too often, a brand or personal brand is built following simplistic, outdated rules: "blue conveys trust," "red means energy," "green feels natural." The truth? It doesn't work that way. In this talk, we'll move beyond color psychology clichés to explore a deeper, more scientific and truly personal approach. According to neuroscience, color perception isn't universal: it's tied to each person's experiences, memories and emotions. This is exactly where the difference lies between a brand that follows conventions and a brand that gets recognized, remembered and chosen. What will you take away? ● A fresh perspective on the strategic role of color in your personal brand ● A method to build an authentic palette that reflects who you are and what you want to communicate ● The tools to set yourself apart from competitors relying on standard solutions ● Hands-on examples, perception tests and real rebranding case studies we'll analyze together All without ever losing sight of what truly matters: readability, accessibility and functionality. Because a brand that works isn't just beautiful. It's effective. **About the speaker** **Gabriele Lakhal** Gabriele Lakhal is a Design Strategist for freelancers and SMEs. He helps professionals and businesses who fear becoming invisible in an increasingly competitive market stand out with authority and win clients. His approach combines brand strategy, user-centered design, color psychology and funnel marketing to achieve tangible business results. ***📍 Join Our Community*** 📱 WhatsApp: [https://chat.whatsapp.com/LptflUCjNOk8BsU43ZE8HG](https://chat.whatsapp.com/LptflUCjNOk8BsU43ZE8HG) 💼 LinkedIn: [Digital Marketing Group Lisbon](https://www.linkedin.com/groups/9249844/) ✈️ Telegram: [https://t.me/+YrJYhbXrDDYwYjg0](https://t.me/+YrJYhbXrDDYwYjg0) 🎟️ Register: [https://dmktribe.com/register/](https://dmktribe.com/register/) **🌍 About DMK Tribe** **DMK Tribe** is an international community of marketers, creatives, entrepreneurs, and curious minds who believe in the power of genuine human connection.
