**Complementary lessons from internal productivity to customer-facing AI** AI is transforming the travel industry, but turning ideas into reliable, measurable systems in production remains hard. In this meetup, engineers and leaders from BlaBlaCar and AMEX GBT Egencia will share practical lessons on how they structure AI efforts, ship real systems, and operationalize agentic workflows—from internal platforms to customer-facing travel products. While both companies tackle similar challenges, they’ll share perspectives from different starting points: * **BlaBlaCar** will discuss its focus on **internal productivity and developer enablement**. * **AMEX GBT Egencia** will share learnings from building **customer-facing, knowledge-grounded GenAI agents**. Together, we’ll cover: * how AI initiatives are structured and measured for impact, * how agentic AI is used for both internal productivity and external user experiences, * what it takes to evaluate, orchestrate, and operate agents reliably in production. Expect concrete examples, honest trade-offs, and shared lessons from teams approaching similar problems from different angles. **Format (Hybrid)** This will be a **hybrid meetup**. If you’re around the Paris area, we strongly encourage you to join in person for discussions, networking, and pizza. Remote attendance is also possible—**RSVP to receive the Zoom link.** **Practical Information** **Date**: March 31st, 2026 🕕 **Schedule**: * 6:00 pm – Welcome & networking * 6:30 pm – Talks start * ± 9:00 pm – Pizza & drinks **📍 Location:** AMEX GBT Egencia, 11 Chemin de Bretagne, 92130 Issy-les-Moulineaux (Agora conference room) **🎯 Audience:** (ML) engineers, data scientists, AI enthusiasts, AI practitioners, leaders **🗣️ Language:** English (questions welcome in English, French, and a few other languages) 👉 RSVP early — **in-person spots are limited.** **Agenda & Talks** **Part 1 — AI Strategy: Organizing for Impact** **BlaBlaCar — Yannick HOFFSESS** In the race to “AI-everything”, a lot of companies are burning cash on demos that never leave the lab. At BlaBlaCar, we took a different route: we are treating AI integration like our carpooling model — focused on efficiency and shared resources. In this talk I will go under the hood of BlaBlaCar AI strategy. This isn't about theoretical models. It is a blueprint of how we integrated AI in our practices. I’ll share our reality: the mindset that actually matters, the projects that delivered good ROI and the hurdles that are slowing down our journey. **AMEX GBT Egencia — Bernard CHEA, Véronique BLIN-ROYER** Great AI products don’t start with a model — they start with the fundamentals that make them reliable. We’ll share how we structured and evolved our AI initiatives to move from experimentation to sustained impact: building strong data and AI platform foundations, adapting our approach for GenAI without reinventing everything, and partnering closely with Product to define success criteria upfront. We’ll also cover the governance and prioritization choices that helped us — and the lessons from what slowed us down. **Part 2 — Agentic AI: Internal and Customer-Facing Use Cases** **BlaBlaCar — Mike BENOIT, Valentin FRIES** In this talk, we’ll first break down our journey in enabling engineering teams with a tailor-made multi-agent ecosystem. How to create an orchestrator agent? Are they good at introspection? How to get the most out of your trusty IDE plugin? We’ll share how we moved beyond standard Copilot usage to significantly increase developer experience. We’ll then demonstrate how agentic tools can be leveraged internally to lift operational bottlenecks, like solving the flakiness of external test systems, assisting customer support in investigating escalations, or optimizing the cost of profile picture moderation. We’ll showcase real-world implementations that directly improve our teams’ quality of life and share how we track the tools’ efficiency to provide measurable business value. **AMEX GBT Egencia — Mohamed HAMHOUM, Riham MANSRI** We’ll share a production-grounded journey of building customer-facing GenAI support, starting with a multilingual RAG-based FAQ system deployed in 10 languages. We’ll do a candid retro on what it really takes to keep a RAG experience healthy once it’s live: defining success criteria, putting the right guardrails in place, building an evaluation approach that works across languages, and maintaining quality over time through monitoring and iterative improvements—not just one-off demos. We’ll then show how those learnings informed our move from Q&A to our first Flight Exchange AI agent in production. Using insights from real chat and live-agent sessions, we’ll explain why flight changes were the right next step, what changed when we introduced an agentic workflow, and how we scoped an initial v1 to deliver value safely while creating a feedback loop to expand capabilities. **Speakers:** **Bernard CHEA** is initially a full-stack software developer since 2005 and joined Egencia back in 2012, building the booking platform, then led the data platform and lastly the AI engineering and AI platform teams. His objective has always been to have a full end-to-end view on all aspects of the business to better serve our customers, asking the same to the teams he’s managing. Outside of work, he likes spending time with friends, a former bachata dancer – connecting to humans and not only computers. **Mika BENOIT** works as a Software Engineer at BlaBlaCar since 2021. He joined the Booking squad, creating since then the backend serving the booking flow for all the buses and trains on the platform. During his free time, Mika likes to learn new maker skill, maintain a too complicated home automation setup and play Dungeon & Dragon. **Mohamed HAMHOUM** is a Machine Learning Engineer at Amex GBT since 2024 passioned by GenAI. He has worked on turning structured search systems into intelligent, agent-driven assistants using RAG and Agentic architectures. He has also led efforts in evaluating and strengthening these systems, ensuring performance, stability, and reliability in high-stakes enterprise settings. Outside of AI, he's a big fan of board games and traveling, though he ironically forgets the names of most of the games he plays, despite being able to design agentic ai systems cross teams. **Riham MANSRI** is a Machine Learning Engineer at Amex GBT, where she develops AI solutions and machine learning models across a range of use cases since her final year R&D internship back in 2022 at Egencia. She enjoys working with advanced ML technologies and applying them to real-world problems. Most recently, her work has centred on Generative AI, spanning the design and evaluation of RAG systems, agentic AI, and the use of A2A to improve agent-to-agent communication and coordination. Outside of work, Riham enjoys movies, especially horror and thrillers, has grown into an F1 fan over the past few years, and is an enthusiastic bootcamp workout devotee. **Valentin FRIES** joined BlaBlaCar as a Senior Software Engineer in 2022 and worked since then on bootstrapping and evolving the Global Distribution System enabling train sales on the platform. Prior to that, he worked for multiple years as Software Engineer in the travel industry, in education, and infrastructure. During his free time, Valentin practices Taï Chi Chuan and likes to start new hobbies — woodworking, bass guitar — that he won't be able to invest in since he has a newborn child. **Véronique BLIN-ROYER** has been working in product management for over 15 years. She started her journey when agile practices were beginning to take root — around 2012, when agile was becoming mainstream. Since then, she had the opportunity to work across different product development teams, from front-end to back-end, always refining her craft as a product leader. Product management has always been a passion for her: “not only do I practice it daily, but I also teach it in a business school and create internal training programs to help others grow in this discipline”. This background has shaped how I approach AI Product Management today — blending rigor, agility, and a deep curiosity for how AI can transform products. **Yannick HOFFSESS** is the Head of Bus and Train Engineering at BlaBlaCar, a company he joined 4 years ago, bringing over 15 years of tech leadership experience from roles in the travel industry at Amadeus. Yannick balances his professional life with a passion for sports, van-life adventures with his family and needles.

Dans cette présentation, j'introduirai les Recursive Language Models (RLM), un nouveau paradigme d'inférence révolutionnaire qui permet aux LLM de traiter des volumes de données dépassant largement les limites de leur fenêtre contextuelle native. Inspirés des algorithmes « out-of-core » (hors mémoire vive), les RLM traitent le prompt comme un objet résidant dans un environnement externe — une boucle REPL Python. Le modèle écrit alors du code pour explorer, décomposer et s'auto-invoquer de manière récursive sur des segments gérables de l'entrée. Les résultats sont impressionnants : les RLM gèrent des entrées jusqu'à deux ordres de grandeur supérieurs à la fenêtre contextuelle de base. Ils surpassent systématiquement l'inférence directe, la compression de contexte, les agents RAG (retrieval) et les agents de génération de code — souvent avec des écarts à deux chiffres — sur des tâches allant du « needle-in-a-haystack » (l’aiguille dans la botte de foin) au raisonnement par paires à complexité quadratique. Plan de l'intervention Le problème de la dégradation contextuelle (context-rot) Le paradigme RLM : comment la récursion et un environnement d'exécution de code changent la donne Passage à l'échelle sur les tâches à long contexte Résultats clés : benchmarks, modèles de référence et domaines de prédilection des RLM Limites, questions ouvertes et perspectives de recherche 👤 Speaker : Sonny Mupfuni (AI Engineer & PyTorch Ambassador) 🎤 Talk 2 : Koog : Intégrer nativement des Agents IA dans votre application Android 🤖📱 [FR]🇫🇷 Dans cette session, vous découvrirez les bases de Koog, le nouveau framework Kotlin open source permettant de créer facilement des agents d'IA directement sur la JVM. Nous aborderons les points suivants : Comment configurer Koog pour l'intégrer dans un projet Android. Comment écrire un agent simple, exécuté une seule fois, qui communique avec une API tierce. Comment connecter l'agent à un modèle de langage (tel qu'OpenAI ou Google Gemini). Comment afficher les résultats dans une interface utilisateur Compose basique. 👤 Speaker : Loic Vyncke (Développeur Android Sénior, eXalt IT) ⚠️ Inscription obligatoire. ‼️ Pour ne manquer aucune notification concernant nos invitations et nos événements, inscrivez-vous sur Bevy.

The Fellowship of the Star Schema: Transforming OLTP Data for Power BI One does not simply build reports on OLTP data. Join us on an epic journey from the depths of raw, normalized tables to the shining halls of a well-modeled star schema fit for Power BI greatness. We will demystify the differences between OLTP and OLAP, walk through star schema vs snowflake (and why Power BI has a clear favorite), and show you the compression differences between normalized and columnar storage that will make you never look at an OLTP model the same way again. We will cover the different types of dimensions, when to use them, and how to handle Slowly Changing Dimensions without losing your mind. You will leave knowing exactly how to identify a bad model, how to convert OLTP data into a clean star schema, and how to forge relationships that rule them all. Whether you are a data wizard, a curious hobbit, or somewhere in between, your models will never be the same.

**PLEASE READ THE FOLLOWING IMPORTANT NOTES:** 1. The dates listed for this series are about 95% reliable. We are completing our 2026 schedule as we speak, so minor adjustments are still occurring. 2. Each class in this series has an attendance fee, though this first offering is free on a first-come, first-served basis. 3. Each class, from BOTH a sign-up and fee perspective, is a separate entity. **Introduction:** HTML5 is the foundational technology for modern web development, serving as the standard markup language for structuring and presenting content on the World Wide Web. Developed through a collaboration between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG), HTML5 provides a robust system of elements (tags) that tell a browser how to display text, images, and multimedia in a clear and meaningful way. It works in concert with Cascading Style Sheets (CSS) for presentation and JavaScript for interactivity, forming the core technology stack for virtually all websites and many web applications today. One of the significant advancements of HTML5 is the introduction of powerful new features and elements designed to improve functionality and simplify development. Key additions include native multimedia support via the \ and \ tags, allowing developers to embed media without third-party plugins. It also offers new form controls for better user input, such as date and email types, and introduces web storage capabilities to store data offline for enhanced performance. These features streamline the process of building rich, interactive web experiences. A significant focus of HTML5 is enhanced semantics and better structural organization of content. New semantic elements like , , , , and \ provide meaningful structure to documents, which aids in search engine optimization (SEO) and improves accessibility for assistive technologies. These elements define different parts of a webpage (e.g., a header for the top, a nav for navigation links, a footer for the bottom), making the code more readable and understandable for both developers and machines. This emphasis on clear structure helps in creating more logical and maintainable websites. Developing websites in today's competitive environment requires taking advantage of every technique you can to get the maximum exposure possible. Our HTML5 class will not only show you what's new in the HTML specification, but also the best way to develop optimized web pages that get the attention your client and/or company requires. **The breakdown of the four-class series is as follows:** **Class 1: Introduction to Web Structure and Basic HTML5** This class introduces the core concepts of web development, the history of HTML, and the fundamental structure of an HTML5 document. * **Topics**: * **Web Architecture Overview**: How browsers, servers, and web pages interact. * **HTML Fundamentals**: Understanding elements, tags, and attributes. * **Basic Document Structure**: Using !DOCTYPE html, html, head, and body. * **Text Formatting**: Headings (h1 to h6), paragraphs (p), and text-level semantics (e.g., strong, em, br). * **Lists and Links**: Creating ordered (ol) and unordered (ul) lists, and linking between pages using anchor tags (a). * **Activity**: Students create a basic personal webpage containing text, a list of hobbies, and a link to an external website. **Class 2: Semantic HTML5 and Multimedia Integration** Class 2 focuses on modern HTML5 elements that provide meaning (semantics) to content, improving accessibility and search engine optimization.

**PLEASE READ THE FOLLOWING IMPORTANT NOTES:** 1. The dates listed for this series are about 95% reliable. We are completing our 2026 schedule as we speak, so minor adjustments are still occurring. 2. Each class in this series has an attendance fee, though this first offering is free on a first-come, first-served basis. 3. Each class, from BOTH a sign-up and fee perspective, is a separate entity. **Introduction:** HTML5 is the foundational technology for modern web development, serving as the standard markup language for structuring and presenting content on the World Wide Web. Developed through a collaboration between the World Wide Web Consortium (W3C) and the Web Hypertext Application Technology Working Group (WHATWG), HTML5 provides a robust system of elements (tags) that tell a browser how to display text, images, and multimedia in a clear and meaningful way. It works in concert with Cascading Style Sheets (CSS) for presentation and JavaScript for interactivity, forming the core technology stack for virtually all websites and many web applications today. One of the significant advancements of HTML5 is the introduction of powerful new features and elements designed to improve functionality and simplify development. Key additions include native multimedia support via the \ and \ tags, allowing developers to embed media without third-party plugins. It also offers new form controls for better user input, such as date and email types, and introduces web storage capabilities to store data offline for enhanced performance. These features streamline the process of building rich, interactive web experiences. A significant focus of HTML5 is enhanced semantics and better structural organization of content. New semantic elements like , , , , and \ provide meaningful structure to documents, which aids in search engine optimization (SEO) and improves accessibility for assistive technologies. These elements define different parts of a webpage (e.g., a header for the top, a nav for navigation links, a footer for the bottom), making the code more readable and understandable for both developers and machines. This emphasis on clear structure helps in creating more logical and maintainable websites.
