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.

Powering AI Agents/Apps w context data from more than just default vector search
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.
Nature walk with Singapore Democratic School
## Nature Walk with Singapore Democratic School
Do you take an interest in topics such as 'self-directed education', 'unschooling', and a child-centric approach towards education? Then join us for a fun and family-friendly nature walk!
During our walk, we will be discussing the book 'Free to Learn' by Professor Peter Gray. In the book, Peter Gray discusses how play is essential for children to become happier, more self-reliant, and better students for life. He argues in favour of self-directed education, which means that students get to decide what, when, and how to learn.
We will meet outside the Botanic Gardens MRT, near the entrance to the Botanic Gardens.
This walk is organised by Singapore Democratic School. You can learn more about the school here:

Prostate Cancer Health Talk with Dr. Peter Lim | Free Event for Men 40+
Prostate cancer is the most common cancer among men in Singapore. Most men have no symptoms in the early stages — and by the time they do, it may already be advanced. **Early detection saves lives. And it starts with knowing your risk.**
This April, take the most important step for your health and join us for a free, expert-led talk by **Dr. Lim Huat Chye Peter** — one of Singapore's most respected urologists and founder of the Society for Men's Health (Singapore).
**📅 Date:** Saturday, 11 April 2026
**🕑 Time:** 1:30 PM – 4:00 PM
**📍 Venue:** Farrer Park Hospital, Connexion, #16-06 (Viv Hall)
**💰 Admission:** FREE
**If you're a man over 40, this talk is for you.**
Most men avoid talking about their health — until it's too late. Don't wait for symptoms. Prostate cancer is highly treatable when caught early, but the window matters. This is your chance to get straight-talking, expert guidance in a relaxed, open setting where all questions are welcome.
**What you'll learn:**
* What prostate cancer is and how it develops silently
* Who is at risk — and why men over 40 need to act now
* When and how to get screened, and what tests to expect
* Treatment options and the latest advances in urological care
* How to have the conversation with your doctor — and what questions to ask
Come alone, or bring a father, brother, husband, or friend. The men in your life need to hear this.
**Seats are limited. This event is free — but your health is priceless. Register now before it's too late.**

CBusData: The Fellowship of the Star Schema: Transforming OLTP Data for Power BI
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.

**Abstract**
GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise.
We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration.
Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team.

Prompt vs. Paintbrush
AI is changing how art is made. But when does it stop being your work and start being the machine’s?
This month we're going to be doing a panel with with digital image, music, and written word artists, talking about at what point, while using AI in the creation process, does the work become not the artist creation?
We encourage audience participation during this event that will be moderated by Chris Slee.
Whether you’re deep in the field or just getting curious, come connect with others building and exploring AI in Columbus.
