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.

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.

Hi everyone, I wanted to start something simple and real. This is a beacon of light or radio messsage for those wanting someone to hear you out. If you're going through a divorce—or have recently been through one—and you're feeling like you don’t quite have a space to talk openly, I just want you to know: you’re not alone. This group was created for exactly that reason. I believe there’s strength in showing up, sharing honestly, and just having a conversation with someone who understands—even if we’re all at different stages of the journey. This first session will be informal. No pressure, no expectations. Just a chance to meet, talk, listen, and connect. Whether you want to share your story or just sit and hear others out, you’re welcome. If you’ve been looking for a sign to reach out or take that first step—this could be it. And if you show up, at the very least, you’ll have someone to talk to. Looking forward to meeting you. — Tony Leo

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.

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.

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. Sponsored by [Transform Labs](https://www.transformlabs.com/services)

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.

**Our April novel is: *The Hong Kong Widow* by Kristen Loesch** **This month’s novel blends gothic atmosphere with historical fiction and chilling horror, set against the haunting backdrop of China. The book is 368 pages in print and 10 hours and 42 minutes on audiobook.** In 1950s Hong Kong, Mei is a young refugee of the Chinese Communist revolution struggling to put her past in Shanghai behind her. When she receives a shocking invitation—to take part in a competition in one of the city's most notorious haunted houses, pitting six spirit mediums against one another in a series of six séances over six nights, until a single winner emerges—she has every reason to refuse. Except that the hostess, a former Shanghainese silent film star, is none other than the wife of the man who once destroyed Mei’s entire life. It is promised the winner will receive a fortune, but there is only one prize Mei wants: revenge. Decades later, the final night of that competition has become an infamous urban legend: The police were called to the scene of a brutal massacre but found no evidence, dismissing it as a collective hallucination. Mei knows what she saw, but now someone else is convinced they know what she did. She must uncover the truth about the last night she ever spent in that house—even if the ghosts of her past are waiting for her there. . . .
