Welcome back to our meetup in April. The date is right before the GITEX AI Asia conference held at the Marina Bay Sands Convention Centre. * **06:00 PM** Registration, dinner, networking * **06:30 PM** Talk starts Talk #1: Powering AI Agents/Apps with contextual data from more than just the default vector search Description: Most solutions showcase vector search as the default search mechanism to power AI applications. But it is often not the most effective solution. In this demo, we will showcase different search techniques and hybrid approaches for retrieving contextual data with MongoDB. Talk #2: Real Practical RAG, from Demo to Production - in a 10,000-person organization and an intelligence org Moving from controlled demos to real-world deployment exposed several challenges that are easy to underestimate. In clean demos, our prompts/queries are often well-formed and datasets are neatly curated, and we test the happy paths. But real users behave very differently. We observed clear gaps between how users express intent and how that intent is represented in the embedding space (leads to irrelevant/missed retrievals). This made retrieval design and chunking strategy critical: how documents are split, indexed, and ranked directly impacted whether the system could “understand” a query. Additionally, as the dataset scaled with many similar or overlapping documents, retrieval became noisier - every vector is similar to a lot other vector - making it harder to consistently surface the right information. These challenges highlight that building a production-ready RAG system is not just about ensuring our datasets and RAG method works, but also user's intent and behavior. TBA: We will have a 2nd speaker talking about AI in real use cases in intelligence orgs either in this meetup or the next meetup. More details for the 2nd speaker are still being prepared.

Kindly understand that This is Not an online event. We created this for the people to communicate with each other (in the comment section) to find their travel mates. However, since the Meetup site requires a date and time. We constantly have to update the date and time to keep the event alive. **Dear friends,** If you have plans to travel somewhere in the world, and you are looking for a travel mate/roommate, you can post it here to let others know, and maybe you can arrange to travel together. It would probably be a good idea to meet up before deciding to travel together but at least this will give you a chance to find a like-minded travel mate. **How to Choose the Right Travel-mate** 1. Have some common interests. 2. Avoid people who tend to extremes. 3. Agree on expenditures before you leave. 4. Make sure your personalities 5. Friends aren’t always good travel companions 6. Don’t go backpacking with a luxury-seeker 7. Make sure you’re able to communicate 8. Agree on a similar budget 9. Avoid picky, crazy and whiny individuals 10. Test each other on a short trip 11. You don’t have to be like a couple of inseparable lovebirds Good Luck and Cheers, Team alpine Trekkers

Hello everyone! Join us for an IN PERSON Apache Kafka® x Apache Flink® meetup on Apr 10th from 6:30pm, hosted by Credit Agricole CIB in Singapore! **📍 Venue:** Mapletree Business City Blk 20 West 20 Pasir Panjang Road Singapore, 117439 , Level 13 \*\*\* **🗓 Agenda:** * 18:30pm-19:00pm: Food, Drinks & Networking * 19:00pm-19:30pm: Zabeer Farook, Technical Architect, Credit Agricole CIB * 19:30pm-20:00pm: ​Dominique Ronde, Staff Solution Engineer, Confluent * 20:00pm-20:30pm: Networking \*\*\* **💡 Speaker:** ​Dominique Ronde, Staff Solution Engineer, Confluent **Talk:** Guardians of the Stream: Kafka, Flink, and the Rise of GenAI **Abstract:** In this session we will explore how Kafka and Flink can seamlessly integrate with GenAI to build intelligent systems capable of real-time learning, automation, and decision-making. Discover the next frontier in data streaming and artificial intelligence, where Kafka, Flink, and GenAI take center stage in shaping the future of industries. **Bio:** ​**Dominique Ronde** is a Staff Solution Engineer at Confluent, a pioneer in enterprise event-streaming platforms. With previous roles as a Big Data Architect and Data Scientist at freeyou, SAP, and Allianz, Dominique brings deep expertise in digital transformation, Java, AWS, and Apache Kafka®. Since 2016, he has worked extensively with Apache Flink and currently serves as a subject matter expert in the APAC region. Dominique is a frequent speaker at conferences worldwide, with a recent focus on innovative data use cases in the insurance industry. Outside of work, he enjoys experimenting with Arduino microcontrollers, IoT home devices, and traveling. \-\-\-\-\- **💡 Speaker:** Zabeer Farook, Technical Architect, Credit Agricole CIB **Talk:** Natural Language Analytics in the Lakehouse : Why is it harder than it looks? **Abstract:** AI agents and the Model Context Protocol finally make natural language analytics on your lakehouse technically plausible — any LLM can discover your schema, plan a query strategy, and return results in seconds. But connect an agent directly to your Iceberg stack and something uncomfortable happens: it returns confident, fluent, wrong answers with no signal that anything is amiss. This talk demonstrates exactly why — wrong metric formulas, invented business terms, incorrect join paths — and introduces the architectural layer that fixes it: the unified semantic layer, exposed as an MCP API. A glimpse at what becomes possible when agents call meaning, not just schema. **Bio:** Zabeer is a seasoned Technology Architect with nearly 20 years of experience in enterprise software across FSI and fintech, including retail banking, wealth management, KYC, regulatory reporting, and payment systems. He brings strong expertise in digital transformation, legacy modernization, and data engineering, with hands-on experience in AWS, Kubernetes, Kafka, Flink, Spark, APIs, and DevOps. Actively contributes to the Singapore tech community, co-hosting Kafka meetups and delivering technical talks, with a strong focus on real-time data streaming and event-driven architecture. \*\*\* ***DISCLAIMER*** BY ATTENDING THIS EVENT IN PERSON, you acknowledge that risk includes possible exposure to and illness from infectious diseases including COVID-19, and accept responsibility for this, if it occurs.

You've been working hard to make changes in your life. You have been putting in the effort. You're doing what seems right. Yet the results do not reflect the work. And deep down, you are starting to wonder why. You are not alone. The problem may not be what you're doing. It's what's quietly working against you. This session is designed to help you find it. A safe space to pause. To reflect. To see what's really blocking you. **What you will walk away with:** • Patterns that have been quietly interfering with your progress • Clarity on what may be misaligned in your current approach • One specific and practical next step you can take immediately Sometimes one moment of awareness changes everything. And this could be your moment in 2026. If this resonates, we invite you to join us.

He's currently writing a book on building personal AI assistants.

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.
