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.

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.

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.
