In our last sprint, we established our cloud-native foundation by containerizing our agents and deploying them to Google Cloud Run. But manual deployments don't scale and require you to dig out the exact docker build and gcloud push commands from your shell history every time you tweak your agent’s prompt. **The Plan:** This session is about creating a **truly robust, repeatable deployment process**. We will wrap up our infrastructure setup by writing GitHub Actions that automatically build and push our agent containers to Google Cloud Artifact Registry on every commit. With a solid, "set-and-forget" pipeline in place, we'll shift focus back to agent behavior. We will build a simple orchestrator agent that uses the A2A protocol to dynamically delegate tasks to the worker agents living in the cloud. **This is a "Lab" session. We will:** * Automate for Robustness: Replace manual command-line wrangling with a GitHub Action workflow to build and push our Docker images to GCP on every push to main. * Build the Orchestrator: Develop a lightweight central agent designed to interpret a complex user prompt and route sub-tasks appropriately. * Live Multi-Agent Communication: Establish an active dialogue over the A2A protocol between your local orchestrator and your newly deployed cloud workers. **The Format** We run our sessions like an anthology series: Every meetup is a standalone sprint. While we often build on previous results, each session provides a complete experience and remains fully accessible to first-time attendees. This is a high-density micro-meetup limited to 6 seats. **What you'll build** By the end of the session, you'll have: * A Repeatable CI/CD Pipeline: A set-and-forget GitHub Action that handles the Docker build and Artifact Registry push automatically, ensuring consistent deployments without the hassle. * An Orchestrator Agent: A coordinator capable of breaking down requests and utilizing external agent tools. * A Live A2A Network: A functioning multi-agent setup where your orchestrator successfully communicates with and aggregates results from your cloud-hosted workers. **Schedule (Saturday, 10:00 - 13:00 CEST)** * 10:00: Quick round of introductions. * 10:15: Intro session: Robust CI/CD with GitHub Actions, Artifact Registry, and Orchestrator routing patterns. * 10:30: Build time: CI/CD automation & building the Orchestrator. * 12:00: Live demos + technical teardown. * 12:45: Wrap-up + takeaways. **Prerequisites** * Accounts: A Google Account (for GCP) and a GitHub Account (for Actions). * Laptop with dev setup: Docker and Git installed and working. * Access to an LLM API: (Gemini, Claude, OpenAI, etc.). * Mindset: This is a lab for engineers, not a tutorial. We learn by building, breaking, and iterating. **Logistics** * Location: We meet at my office in the Grunewald area near Martin-Luther-Krankenhaus. The exact address will be shared privately with attendees to maintain privacy. Capacity: Limited to 6 seats.

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

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

AI is changing how art is made. But when does it stop being your work and start being the machine’s?

**The Data-Driven Brand: Using Analytics to Shape Perception** Can you use analytics to improve tacos? This being CBUSDAW, we think the answer is probably “yes”, but we’re not sure how to implement or test this theory. For our April meetup we’ve got Sara Kear, CMO of Condado Tacos, to investigate this delicious question. Sara will explore how she blends quantitative data and qualitative customer feedback to shape brand positioning and drive business decisions. We all know that marketing and analytics go way beyond attribution. Sara will show how Condado uses customer insights to inform product and pricing strategy. She’ll also highlight how Condado leverages customer feedback at scale to influence operational priorities, positioning marketing as the voice of the customer across the organization. In the last 12 years Condado has gone from one location in Columbus to 52 locations across 10 states, so we’re guessing there’s more to that growth than really good guac (though the guac probably helps). Ultimately, this talk focuses on the intersection of art and science—using data to inform creativity and build a brand that resonates with customers in a measurable way. **About Our Speaker** Sara Kear is Chief Marketing Officer at Condado Tacos, where she oversees brand, restaurant design, menu and pricing strategy, off-premise including catering, and customer data strategy. Since joining in 2021, she has helped grow the brand from 19 to 52 locations while building a data-driven marketing organization focused on loyalty and customer insights. Condado has since been named to the Inc. 5000, recognized as Breakout Retailer by Chain Store Age, and consistently ranked among FastCasual’s Top 100 Movers & Shakers.
