What if the best product requirement was a working prototype? Amazon built an empire on one principle: start with the customer and work backwards. Identify the durable need. Resist building until you know what you're solving - and for whom. Vibe coding doesn't abandon that discipline. It supercharges it. Join us for an in-depth discussion on how natural language becomes structured specs, specs become architecture, and architecture becomes working software - in real time, in the room, on your machine. Whether you're validating a product idea or accelerating a team's delivery, this is where the “Working Backwards” mindset meets the AI-native development stack. **Featured speaker:** * [AJ Bubb](https://www.linkedin.com/in/ajbubb/), Innovation Strategist and AWS veteran - for a hands-on session exploring Spec-Driven Development with AWS Kiro. \~ "*We're not just talking about it. We're building with it*!" **Location:** AWS Skills Center, 1550-G Crystal Dr, Arlington, VA 22202 **Drinks and Networking After:** Tacombi, 1550 Crystal Dr, Arlington, VA 22202 **Description:** Join us at AI Innovators Network for our upcoming meetup in the Mosaic, which is dedicated to exploring the latest trends in Artificial Intelligence. Whether you're an AI enthusiast, a professional, or someone curious about the intersection of technology and AI, this event is perfect for networking, learning, and sharing insights.

This session introduces Squad: an open-source framework for multi-agent orchestration that lets you define teams of AI agents with specific roles, responsibilities, and expertise. We'll progress from Copilot basics to the Copilot CLI, explore how Agents add autonomy, and see how Instructions and Skills let you customize agent behavior. Then, the climax: a live demo where a Squad team of 3 agents (Lead, Developer, Tester) stands up and builds a working application in real-time, showcasing true multi-agent collaboration. Whether you're new to AI or exploring how to scale your use of Copilot, this session will show you what's possible when agents work as a team. **YouTube Link** TBD

In this local meeting, you will discover knowledge that you can use to get over the past. The key to improving your personal motivation, self-confidence, and happiness is to get over your painful memories.
