Most investing advice you find online is designed for US residents: 401(k)s, Roth IRAs, US-domiciled ETFs, zero capital gains tax in many states... But if you live in Luxembourg, almost none of that applies to you directly. And yet, Luxembourg offers its own powerful set of tax advantages that most residents never fully use, simply because they don't know about them. The problem? Finding clear, practical guidance on investing as a Luxembourg resident is surprisingly difficult. The rules are different, the products are different, and the tax implications can catch you off guard if you follow generic advice from American YouTube channels or Reddit threads. This session is a structured, open discussion designed to highlight the key differences and help you understand what actually matters when building a portfolio from Luxembourg. 🧭 Format of the Event This is a casual, discussion-based gathering with no long presentations. We'll sit around the table, and your host Romain will kick things off with a short introduction covering: * Why most online investing advice doesn't translate to Luxembourg * The key tax advantages available to Luxembourg residents (and how they compare to the US) * Common pitfalls expats and residents fall into when following US-centric strategies From there, we open the floor for discussion. Bring your questions, your experiences, and your curiosity. Recommended Preparation To get the most out of our discussion, think about the investing advice you've come across online and whether you've ever wondered: "Does this actually apply to me here in Luxembourg?" * Continue the Conversation: For more content on building evidence-based portfolios as a Luxembourg resident, you can follow me on LinkedIn here: **[Romain Lucas](https://www.linkedin.com/in/romain-f-lucas/)** 👥 Who Can Join? Everyone is welcome. This discussion will be especially valuable if you are: * A Luxembourg resident or expat who invests (or wants to start) but isn't sure how local tax rules affect your strategy. * Someone who has been following US-focused investing advice and wondering what applies here and what doesn't. * A professional who wants to understand the specific advantages Luxembourg offers for long-term wealth building. 📌 Practical Info * 🗓️ Date: Tuesday, March 10th, 2026 at 18:30 * 🗣️ Language: The event will be in English. * **📍 Location: Junco (Luxembourg). 6 Rue du Fort Niedergruenewald, 2226 · Luxembourg. Ask at the venue if you need directions.** * 🍻 Drinks: Drinks are self-paid at the venue bar. * 👥 Limited Seats: Please RSVP so we can manage space. If you can no longer make it, please cancel your reservation to free up your spot for someone on the waitlist.

Hi everyone — we just recently passed the 20 members milestone. I'm super excited to discover there are so many people curious about Clojure and functional programming in Luxembourg! What I propose as our next steps is to try to schedule our Meetup #1 in the next 4–8 weeks (end of February - March, after-work/in the week-end, 60–90 min). In preparation, let's try to know each other: please reply to the event questions - or head to the discussion thread.

**Schedule** 5:00 pm - 5:30 pm - Sign-in/Meet and greet/networking 5:30 pm - 7:00 pm - Break the Cloud Lock-in: Building Adaptive Intelligence Orchestration with DIO 7:00 pm - 7:45 pm - Leaning on the SQL: Crafting Resilient Data Layers **Talk and Speaker Details** **Time**: 5:30 pm est. **Title**: Break the Cloud Lock-in: Building Adaptive Intelligence Orchestration with DIO **Summary**: AIaas are often stuck in a binary choice: pay the "token tax" for convenient Cloud APIs or manage the complexity of local open-source models (Llama/Mistral) yourself. The future belongs to a hybrid architecture—but the routing logic shouldn't be spaghetti code. In this session, we introduce DIO (Distributed Intelligence Orchestration), a new open-source framework designed to bridge on-premise infrastructure and cloud capabilities. We will move beyond theory and look at the code behind the Federated Decision Engine (FDE)—the algorithm that allows you to dynamically route prompts based on privacy, cost, complexity, and more. **Session Takeaways:** \- The DIO Architecture: A technical deep dive into the open\-source framework that decouples your application from specific model providers\. \- Live Integration: How to implement the DIO SDK to build a "Smart Router" that connects the best of both world for Cloud & On Prem Intelligence\. **Speaker**: Snow Zhao **Speaker Bio**: Founder & CEO of AIgentic \| Ex\-Meta engineering leader\. Building the future of professional services with precision & trust\. Snow has decades of Silicon Valley experience building and scaling technology organizations at Facebook, Block (Cash App), and Groupon. She is currently building at AIgentic, an applied AI company designing robust, trustworthy AI systems for professional industries. She leads global teams that delivered secure, high-performance systems used by billions, from product infrastructure behind Messenger’s rewrite and end-to-end encryption, to architecting enterprise AI platforms that bridge traditional sectors with digital transformation. Her work has spanned mobile, security, open-source, federated architecture, AI-powered automation, cross-platform software ecosystems, and more — always guided by the principle that engineering excellence is a human discipline as much as a technical one. \-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\- **Time**: 7:00 pm est. **Title**: Leaning on the SQL: Crafting Resilient Data Layers **Summary**: Most apps need to persist data. The mechanisms for persisting vary, from key-value pairs to relational databases to files and more. SQLite is the de-facto standard for persistence in mobile apps: it ships with every Android and iOS app. This session looks into best practices for SQLite data persistence, drawing from practical, digestible, real world examples. We look into when one should lean on the SQL versus when to perform data manipulation in application code. We look at some examples of constraints that you might have written in Kotlin/Swift, and how expressing them in SQL instead can offer data consistency and integrity benefits. A major focus of the session is on migrations. Data schemas inevitably evolve, and executing migrations carefully is essential, as mistakes can have severe consequences, including data corruption. We look into best practices for migration, including when to do migration in application code versus in SQL. We also examine some real world migration examples beyond the simple case of adding a column with a default value. Finally we look at migrations that cross data sources. This could occur if for example you were persisting data in a key-value store but you now want to migrate that to a database table. This must be done in application code but can you still take advantage of database migrations? Can you cover your migration code with unit tests? **Speaker**: Kiran Raon **Speaker Bio**: Two decades as a developer, got into Android in 2010. Adopted Kotlin in 2017, had my first attempt at KMP in 2019 (when it was still called KMM). Worked on and off with iOS and web client technologies throughout my career, also dabbled in other cross platform technologies. Full-fledged Mobile developer since 2023. **How to find us:** 1680 Capital One Drive, McLean, VA 22102 We'll be located in C2 **100 D/E**. The area is publicly accessible.

They are missing the bigger picture. OSD is a powerful, untapped environment for full-stack application development. In this session, we peel back the architecture of **an enterprise-grade risk, compliance, and security platform built entirely *on top of* OSD**. We moved beyond simple plugins and pushed OSD to its limits to create a seamless, interactive application experience. Join us for a deep dive into the engineering reality of the OpenSearch stack, including: * **The Analysis:** Why the OpenSearch stack beat out the competition. * **The Build,** **Beyond Visualization:** How to implement custom React components to build complex workflows and interactive UIs within OSD. * **The Integrations:** Integrating Wazuh for agent management and ingesting data at scale. * **The “Gotchas”:** Honest, real-world lessons on data handling, state management, and what to look out for. **If you are ready to push your plugins from “reporting tools” to “robust software,” do not miss this session!**
