Welcome back to Rumble. This month our focus is to help you climb stronger, descend safer, and move more confidently on hikes. We’ll keep our 4 core stations — feet and calves, engine, climbing strength, and downhill control — so you can actually feel progress over the weeks, not just get through a workout! **Meeting Place:** as seen in the image (Right next to Old Hill Street Police Station; opposite Funan) Accessible via different MRT lines and bus stops 3 min walk from Clarke Quay Stn Exit E **Duration:** 1.5h **Level:** Mixed Levels (but make sure you are physically well before attending) **What to expect:** 1. Warm-up & dynamic stretching 2. Stamina, Stability and Single Leg strengthening exercises with Stairs/Steps :) 3\. Jogging/brisk\-walking between stations **Items to bring/wear** * comfortable sports attire and appropriate shoes * (Arm-length) Towel and water bottle * Most of us will be carrying our bags as part of hike training (you can choose to leave them in your car if you’re driving or bring a small bag) Make sure you are able to run with your bag! (e.g. BACKPACK) **Note:** * In the event of wet weather, the event will be cancelled. However, if it is just a light drizzle, we may still proceed with caution or head to AU office for Signature Indoor Workout. * If you will be late or unable to make it, please inform me in advance (WA +6597318648) or update your RSVP by 8 p.m. the night before so that I can inform the next person on the waitlist. * We’re capping this at **20 pax per session** so it stays focused and manageable. * Priority will go to 2026 AU trip participants and Elite AU club members. If there are slots left, it will be given to members of the publi.c If you’re on the waitlist, it may not move strictly in order as trip participants are prioritised. We will start on time so come at least 5 minutes earlier! If you’ve done Rumble before, you already know what this is about. If you haven’t — come try once. You’ll either love it or hate me slightly. Both are acceptable. Join us for more adventures at: https://bit.ly/3Rv6XrT

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.

This is not a typical networking event. We’re bringing together a small, curated group of founders, CTOs, and builders working on real products — to talk about what they’re building, what’s starting to break, and what they’re figuring out. No presentations. No sales pitches. No noise. Just meaningful conversations with people who are actually building. A curated gathering of founders, CTOs, and builders working across AI, SaaS, and technology. No pitches. No panels. Just real conversations.

Some quiet morning time doing writing / working at a cafe.

AI is rapidly changing how software is built, but many developers are still unclear on how to move from using AI tools to actually building AI-powered applications and agents. This talk breaks down the key concepts every developer needs to understand, including large language models, tokens, embeddings, retrieval-augmented generation (RAG), and AI agents. AI 201 because we have presented a AI 101 last year more on AI Coding Tools and its concepts. The session will be delivered by three speakers from the Women Developers Singapore (WDS) community. The talk will be structured as a cohesive walkthrough: from how AI models understand language, to how they access data, and finally how developers can build production-ready AI applications and agents.

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.
