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. Connect with like-minded individuals from DC, Northern Virginia, and Maryland as we dive deep into the opportunities and challenges of integrating AI. Don't miss this opportunity to be part of the conversation driving innovation and progress in Artificial Intelligence.

*Beyond Curfews and Toward Real Community Safety*. While youth curfews in DC continue to be pushed in the name of “public safety,” we must shift the focus toward what real safety looks like when communities lead. Instead of policing and punishment, this discussion explores how investing in youth, housing, education, and opportunity can prevent harm at its roots. Grounded in PACA’s vision, this **Assata Shakur Popular Education (ASPE)** session will examine how residents can take decision-making power over safety, resources, and accountability. Together, we will identify concrete steps to move beyond curfews and build community-led, youth-centered systems of care and safety. Food will be provided! *Food will be provided!*

Join us for an engaging panel discussion on **AI Agentic Coding** and how autonomous AI systems are transforming the way software is built. Experts in AI, software engineering, and developer tools will share insights on how agentic AI—systems that can plan, reason, and execute coding tasks—is reshaping modern development workflows. The discussion will cover topics such as AI-assisted development, productivity gains, challenges around reliability and governance, and what the future of software engineering may look like with AI agents as collaborators. Whether you’re a developer, tech leader, or AI enthusiast, this session is a great opportunity to learn, ask questions, and explore how agentic AI is redefining coding

Bring your Raspberry Pi, Arduino, microcontroller, or any other electronic project and join fellow electronics makers for a night of creativity and collaboration! This session is open forum to share your current projects—whether complete or in progress, it’s all interesting! Whether you’re deep into embedded systems, exploring new ideas, or just getting started, you’ll find a welcoming space to collaborate, share, and get inspired. **New to electronics or curious about tinkering?** You’re absolutely welcome. If you’re a beginner and want to experiment, I’ll have a couple of starter kits available so you can try things out—whether that’s blinking your first LED, putting something on a display, or experimenting with simple sensors. No pressure and no experience required—just an interest in learning and building. While we continue to pursue a more permanent venue for this Meetup, we’ll be using public library facilities based on availability. This session will be at the Worthington Park Library in the Olentangy Meeting Room.

**Important time note:** Please plan on arriving between 5:30 and 6:00 as the elevators lock after 6 and you'll need to message us and we'll need to come get you. The building address is 4450 Bridge Park The entrance is 6620 Mooney St, Suite 400 You will need to scan your ID at the door to get a visitor badge. **Abstract** GitHub Copilot is powerful, but what if you could scale from a solo AI assistant to an entire team of specialized agents working in parallel? 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
