Title:
How to design nice PowerPoints
Synopsis:
"Death by PowerPoint" is a commonly used expression to convey boredom with slide decks. But the issue isn't PowerPoint per se, but that it's not being used correctly. When used properly visual aids can be one of the greatest assets to a talk.In this presentation I'll be going through the basics of good information design and how that applies to slide decks, namely how to reinforce main points, how to explain complex ideas and also some points to avoid - even more importantly when not to use a slide deck.Speaker 2: Verissimo Ribeiro - VP of Engineering at Landytech
Title:
Spring AI: Structuring Unstructured Data
Synopsis:
I’ll show how to build AI solutions with Spring to transform unstructured data into structured information. I’ll walk through key techniques like Single Shot Prompts, Assistants, Workflows, and Agents. Also a quick tour of Models, Providers, Roles, Tools, and strategies like RAG, CAG, and MCP.
Additional notes:
This talk is based on my experience building an AI assistant and a solution that imports any bank or credit card statement into a system-friendly format.Speaker 3: Shabana Govani Khatau - Full Stack and SharePoint Developer at East West Rail

Speaker One:
Trisha Gee - Java Champion, Lead Developer Advocate at Gradle
Talk: Developer Productivity With IntelliJ IDEADeveloper productivity is a hot topic right now, but what does it mean? Is it all just about squeezing more lines of code out of us poor, overworked developers? Or could it, in fact, lead to developer joy?
In this session, Trisha will show some of her favorite IntelliJ IDEA tips for improving her own productivity. She'll use these examples to talk about what productivity is, what it is not, and why it's even more important to us as developers than it is to the organizations that pay our salaries. And it's of course important to them, too!
Attendees will gain a deeper understanding of how IntelliJ IDEA helps them to be effective, productive, and happy. Trisha wants you to look at your toolchain and ask yourself, “Does this enable me to be creative and happy?”

Swetha Golla - Expert Application Architect at Discover Financial Services
Talk: Building Resilient Systems: The Power of Architecture “-ilities” in Cloud-Native and Hybrid EnvironmentsIn today’s digital landscape, businesses are increasingly adopting cloud-native and hybrid cloud strategies to meet complex and evolving needs. Designing resilient, reliable, and scalable architectures in these environments is essential to achieving operational excellence. This session delves into the architecture ilities—Scalability, Reliability, Availability, Maintainability, Portability, Security and how they impact costs —that serve as the foundation for robust system design.
We’ll explore how these critical non-functional requirements influence architectural decisions and enable success in both cloud-native and hybrid deployments.
This session empowers attendees with actionable strategies to design systems that are not only functionally sound but also resilient to failures and adaptable to change, ultimately delivering better value for customers and businesses alike.
Key Takeaways and Benefits:
Join me to explore the principles and practices that will transform your approach to designing cloud-native and hybrid systems in today’s dynamic technology ecosystem. Key takeaways include:
1. Gain a clear understanding of the core architecture focus and their impact on building resilient systems in cloud-native and hybrid cloud environments.
2. Enable developers and architects to deliver robust systems that enhance performance, uptime, and user satisfaction, driving measurable business and customer benefits.Speaker Two Bio:
