Welcome back to our meetup in June. * **06:00 PM** Registration, dinner, networking * **06:30 PM** Talk starts Talk 1: Practical AI from Gemini Embedding 2 for Simplified RAG Search with Rich Context and Less Preprocessing - Imagine the possibilities if you could find a document using an image, or find audio from a report, or find a video with a sentence. \- Simplifies RAG Systems \(one multimodal retrieval pipeline instead of multiple fragmented systems\) \- Less preprocessing \(e\.g\. no transcription needed\) less infrastructure complexity \- Richer context \(text \+ visuals \+ audio\) \- A major step from “document chatbots” to truly context\-aware AI systems Gemini Embedding 2 changes what Retrieval-Augmented Generation (RAG) can fundamentally do. Instead of treating text, images, audio, video, and documents as separate systems, AI can now retrieve and reason across all of them together in one shared understanding layer. This means users can search videos with natural language, retrieve diagrams from spoken conversations, match screenshots to documentation, or ground AI agents with real-world multimodal context — capabilities that were previously complex or unreliable without multiple specialized pipelines. Talk 2: Designing Memory Systems for AI Agents AI agents need memory to maintain context across sessions, learn from experience, and handle long-running tasks. The challenge? Deciding what to remember, where to store it, and how to retrieve it when it matters. In this workshop, you'll learn a practical framework for architecting memory systems that actually work in production. We'll cover: \- Types of memory in agentic systems \- Storage patterns: Where to persist memories and how to structure them for retrieval \- Retrieval strategies: Combining vector search with metadata\, recency\, and other signals \- Memory lifecycle: When to create\, update\, or prune memories to keep your system performant You'll apply this framework by building memory into an AI agent and seeing how different design choices impact behavior. You will be provided with all the resources required to successfully execute the hands-on portions of the workshop, including Jupyter Notebook templates with pseudocode. During the workshop, you will replace the pseudocode in the templates with your code. At the end of the workshop, you will also be able to check your learning and earn a skill badge to share with your network! https://learn.mongodb.com/courses/memory-for-ai-applications ## **Future Talk: TBA** **Awaiting confirmation: Federated Layer to Manage a Multi-Agent Synthetic Workforce** Agents are starting to act as workers in real production systems, and workers need a management layer. The question everyone should take back to your laptop: in my own agent stack, what happens on the second concurrent write, and can I prove, today, under whose authority my agent acted? How do I manage my synthetic workforce in production.

Halo Data Engineers Singapore! We are excited to welcome **Jason Jebanesan JEBANESAN** from **Credit Agricole CIB** & **Kelvin Kok,** from **Axrial** to talk about: ***Stop Tuning Your RAG Start Orchestrating - by Jason*** RAG was supposed to fix hallucinations, instead it introduced a new class of silent production failures. Tuning won't save you. RAG is a control-plane problem, and MCP is the wire underneath. ***10x Your Data Engineering: Rapid Glue ETL Prototyping with Kiro - by Kelvin*** ​The longest mile in data pipeline construction is building the transformation layer. Manually configuring AWS Glue jobs can bottleneck an entire project. In this lightning-focused talk, we’ll show you how we use Kiro to completely bypass the boilerplate. We will walk through how we feed technical constraints into Kiro to rapidly generate highly optimized AWS Glue ETL logic, ensuring efficient execution while keeping developer velocity at an all-time high. **Expected agenda:** **6.30pm - 7.00pm** \- Registration\, Food & Networking **7.00pm - 7.45pm** \- Presentation & QnA by Jason **7.45pm - 8.30pm** \- Presentation & QnA by Kelvin **8.30pm – 9.00pm** \- Post\-event Networking Hope to you all soon! Cheers! DESG
