**Agenda:** • 5:00 PM - Doors Open (in-person attendees). • 5:30 PM - **Deep Dive into Claude Code** • 6:30 PM - Networking • 7:00 PM - Doors Close **Talk Overview:** **Deep Dive into Claude Code** Ever wondered what happens under the hood when Claude Code runs your next Android task? This talk dives into the internals of Anthropic's AI coding agent — its bootstrap pipeline and agent loop. You'll see how fork agents share prompt-cache prefixes to cut input token costs and how four-layer context compression keeps long conversations from exhausting the window. You'll leave with a mental model of how this production AI agent actually works. Whether you're building custom MCP integrations, orchestrating multi-agent tasks, or just trying to get more from the tool you use every day, you'll have a toolkit of patterns to apply to your own Android workflows. **Speaker**: Mohit Sarveiya **Speaker Bio:** Staff Android Engineer AirBnb & Google Developer Expert **How to find us:** 1680 Capital One Drive, McLean, VA 22102 We'll be located in C2 **100 D/E**.

A small team of AWS Solutions Architects not traditional software engineers, built AIRE Traffic Control (ATC), a production agentic AI platform now serving thousands of builders. We used AI at every stage: spec-driven development, AI-generated code, automated testing, and agentic workflows. In this talk, we'll share the real story, the architecture, the failures, the breakthroughs, and what we learned about driving adoption from 32% to 92% in 10 weeks. You'll walk away with practical patterns for building multi-agent systems, using AI-DLC methodology, and empowering non-traditional dev teams to ship production-grade applications.

\-\-\-\-\-\- [REGISTER FOR THE EVENT HERE (ON LUMA)!](https://luma.com/h4938tvr) \-\-\-\-\-\- Join us for an evening of collaborative problem-solving as we work on a variety of civic tech projects together. Project needs vary but often include brainstorming, researching, writing, coding, or analyzing data. Check out [our website](https://www.civictechdc.org/projects) for a list of projects which may make an appearance! Meet other civic tech enthusiasts. Learn new skills. Contribute to a project to improve a local civic issue. **All are welcome and collaboration is encouraged.** Laptops are recommended but not required. **Where do I register?** To better serve our growing community, we’re transitioning our event registrations to [Luma](https://luma.com/civic-tech-dc)! **We still love Meetup** Meetup has been an incredible platform for us to build and connect with our community. We’ll continue sharing upcoming events there so that new people can find us, but [Luma](https://luma.com/civic-tech-dc) will be our primary registration platform moving forward. **Why we're making the switch** Meetup’s registration system has some limitations, and we need more flexibility to manage sign-ups and engagement. \-\-\-\-\-\- [REGISTER FOR THE EVENT HERE (ON LUMA)!](https://luma.com/h4938tvr) \-\-\-\-\-\-

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
