**Special topic for this week: TODO!** Have you ever wondered what happens after you write your program in any programming language and hit "Run"? Welcome to the new group dedicated to Compiler Engineering so we can discuss language design, static analysis, VMs, and code generation. Topics related to hardware architecture and FPGA are also welcomed! **Join us weekly and learn about:** * The vision for this group. * A crash course on how to start learning compiler dev (including top book recommendations). * An open networking session for showcasing projects and finding collaborators. * Weekly topic to learn about particular aspect of programming languages or hardware **Who is this for?** * Anyone building DSLs or new languages. * Anyone curious about low-level systems and programming * Anyone hiring for compiler/toolchain roles (come pitch your jobs!). * Anyone who wants to learn more about programming languages nature! This isn't a lecture—it's a conversation. Come share your projects and get motivated! This group is not super serious, so if you want to just yap about how bad is the new C++ standard you can find some listeners here. See you!

This session breaks down the two critical layers of a scalable agentic architecture: The Execution Layer, which provides a standardised platform for agent runtime scaling, and the Orchestration Layer, which leverages event-driven architecture to keep agents reactive and synchronised. Explore the transition from solo AI-assisted development to a centralised platform model that translates individual productivity gains into aggregate organisational benefits. This involves building runtimes for a multi-assistant era, where governance is a feature rather than an operational tax. Complementing this, we’ll examine how event-driven architecture acts as a backbone to update knowledge bases in real-time with high-quality data. Learn how this approach simplifies the incorporation of new agents, allowing you to scale from single-agent to multi-agent applications without increasing operational load or compromising data governance. This session concludes with a community discussion designed for practitioners to exchange shared challenges, and learn from each other’s experiences in building robust AI systems. We’d like to hear from your experiences too! So come join in on the discussion today: **[go.gov.sg/stackmeetup-7may2026-mc](https://go.gov.sg/stackmeetup-7may2026-mc)** Who should attend: AI engineers, platform architects, and data practitioners focused on transitioning AI agents from experimental scripts into resilient and production-ready enterprise systems. **Programme** 6:30pm: Networking 7:00pm: Introduction By STACK Community 7:05pm: Opening 7:15pm: Scaling AI Development​ By Ng Shangru, Staff Software Engineer, AI Programme, GovTech Singapore 7:35pm: From Demo to Production: Scaling Agentic AI with Event-Driven Architecture Seamlessly​​ By Shelvia Hotama, Senior Solutions Engineer, Confluent 7:55pm: Discussion on Building Robust and Scalable AI Systems With Shangru, and Shelvia 8:15pm: Q&A 8:30pm: End of STACK Meetup Click **[here](https://go.gov.sg/stackmeetup-7may2026-mc)\*** to sign up! \*Registration will be accepted via GovEntry only.

Customer identity resolution becomes increasingly complex as organizations scale across multiple systems, regions, and data formats. Traditional rule-based approaches often fail to keep up with data variability, require constant manual tuning, and struggle with real-time processing needs. This session presents a practical approach to building a scalable identity resolution pipeline using AWS services and modern AI techniques. The architecture combines data ingestion through Amazon S3 and AWS Glue, transformation pipelines using Spark on EMR, and machine learning models deployed via SageMaker for entity matching and standardization. Graph-based relationship modeling is implemented using Amazon Neptune to improve resolution accuracy by incorporating household and shared attribute context. We will walk through how machine learning models can be used for name and address normalization, how intelligent blocking strategies improve matching efficiency, and how feedback loops can be introduced to continuously improve accuracy. The session also highlights how serverless components such as AWS Lambda can be used for orchestration and real-time processing. **SPEAKER BIO** Mosaic Syed is a Senior Data Engineering and Cloud Solutions Architect with over 20 years of experience designing and delivering scalable, secure, and high-performance data solutions across global enterprise environments. https://www.linkedin.com/in/mosaic-basha-syed-92300856 **CALL FOR SPEAKERS** Learn more: [https://www.awscolumbus.com/get-involved/](https://www.awscolumbus.com/get-involved/) **THANK YOU** *VEEAM* for hosting our meetup!

Join us for a practical, beginner-friendly guide to choosing the right large language model. We’ll compare major models like ChatGPT, Claude, Gemini, and Llama, talk about when to use hosted APIs versus local models, and break down the tradeoffs around cost, speed, quality, privacy, context windows, coding ability, and reliability. You’ll leave with a clearer mental model for picking an LLM based on your actual use case instead of hype, benchmarks, or brand names. No deep AI background required. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.

Practical AI for Power BI Developers A year ago, “agentic AI” was mostly hype for Power BI teams. Today, it deserves your undivided attention. For Power BI pros, there is now a real opportunity to reduce repetitive development work, accelerate delivery, and help developers do more, but only when strong DataOps practices are in place to make AI workflows effective. This session is a no-nonsense introduction to effective AI patterns for Power BI and Fabric development. Along the way, we will make sense of the growing pile of terminology, including skills, plugins, hooks, and MCP. You will see examples of how modern AI tooling can help with development tasks across Power BI and Fabric, along with the prerequisites, guardrails, and DataOps principles needed to use it responsibly. Whether you're burned out on AI hype or already using Copilot CLI daily, this session will show you the foundations that are finally making AI-assisted development genuinely useful.
