Sydney MongoDB User Group

Hi MongoDB Users,

Join us for the Sydney MongoDB User Group event as we explore best practices and use cases of app development with MongoDB. Whether you're a software developer, tech enthusiast, or simply curious about new technology, this event is for you.

We're excited to announce an in-person meetup session scheduled for Tuesday 11th October 2025. This is a FREE event.

The agenda for the evening are TBC

• 6:00pm - Announcements
• 6:10pm - AI & The Future Of Finance Broking by LoanOptions.ai
  Modern applications demand scalability, speed, and flexibility, yet delivering all three with a lean team is no small feat. At LoanOptions.ai, we’ve achieved it by pairing AWS’s managed services with MongoDB Atlas to power industry-leading, transformative solutions. These include AILO, our white-labelled finance application embedded in hundreds of partner websites; HAILO, Australia’s first five-minute home loan application that has redefined how both customers apply for loans; Ask AILO, our 24/7 broker development manager that can answer complex lender policy questions accurately, without hallucinations; and Synapses, our MCP-enabled API hub that allows AI agents to securely access tools, integrate data, and perform actions across systems.
• 6:40pm - Rank & Reason: Mastering Hybrid Search in MongoDB
  Is your search functionality falling short? Traditional keyword search is precise but often misses the user's true intent, while vector search understands context but can lack the specificity needed for perfect results. How do you get the best of both worlds?
  Enter Hybrid Search. This session demystifies how MongoDB Atlas Search masterfully blends the precision of full-text (lexical) search with the contextual power of vector (semantic) search. We'll dive deep into the core mechanism that makes this possible: Rank Fusion. You will learn how techniques like Reciprocal Rank Fusion (RRF) intelligently merge and re-rank disparate result sets to deliver a single, highly relevant list to your users.
  Join this session to:
  Grasp the fundamental concepts of hybrid search.
  Understand how rank fusion creates a unified, superior search experience.
  See a practical demonstration of building a hybrid search query in MongoDB Atlas.
  Discover best practices for creating smarter, more intuitive applications.
  Whether you're looking to enhance a product catalog, a knowledge base, or a Q&A system, this talk will give you the tools to build a truly next-generation search experience.
• 7:20pm - Networking / Refreshments
• 8:00pm - Wrap Up

Please RSVP if you plan to attend so we can plan for appropriate food & beverage supplies.
