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.

For decades, application security has been built around a simple assumption: humans are the primary producers of software. We train developers, review their pull requests, model threats in design meetings, and build controls around human decision-making. That assumption is rapidly breaking down. As AI coding assistants evolve into autonomous software agents, organizations will gain access to an effectively unlimited engineering workforce capable of producing software at a speed no human team can match. The pressure to adopt these systems will be driven not by curiosity, but by competition. Companies that successfully harness agentic development will ship faster, iterate faster, and potentially outpace those that do not. This shift forces a fundamental rethinking of application security. The future of AppSec is not securing developers—it is governing an agentic workforce. Threat modeling, code review, security testing, and change management will not disappear, but they will need to operate at machine speed and increasingly be performed by systems rather than people. In this talk, Ken Johnson, CTO of DryRun Security, explores what the next decade of application security may look like, the assumptions that will no longer hold, and why security professionals must understand these systems deeply if they hope to influence the future rather than react to it.

**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**.

**The next GeoDC will be held on Wednesday, June 10 from 6-9pm at Sudhouse DC (1340 U St NW, Washington, DC 20009) with the program starting at 7pm.** * Join us early from 6-7pm to grow your network, socialize and grab drinks and appetizers. * Throughout the evening, we'll be sharing job announcements and details of other GIS/Geo upcoming events we're tracking. * We look forward to seeing you on the 10th! **Our Program will feature these presentations:** **The Secret History of the Blue Dot - William H. Tewelow, GISP (GPS World)** This presentation takes the audience from an iconic movie scene they recognize but never understood, through the hidden origins of GPS, and returns them to the blue dot in their own hand, seeing it for the very first time. There is a blue dot on your phone right now. It knows where you are to within a few feet. You have never questioned it. You have never wondered where it came from. You should. Its origins are classified. Its lineage runs through the Cold War, nuclear submarines, and a doctrine built on the promise of mutual annihilation. The technology that tells you where to turn was designed for something else entirely. The technology did not change. Only the purpose did. **GEOINT Symposium's Golden Ticket Program - Katie Weintraub (ESRI)** This is a firsthand account of USGIF's GEOINT Symposium Golden Ticket — a program built for early-career professionals who want to level up their careers. Participants get free admission to GEOINT Symposium, mentorship opportunities, a network of fellow Golden Ticket alumni, and a cohort of peers to grow alongside. This talk breaks it all down fast — what it is and why it's a stellar experience for young professionals breaking into or already working in the geospatial intelligence realm. **From GIS to AI: Lessons from MIT’s Applied Data Science & AI Program**- **Julia Brodsky (Navy Federal Credit Union).** A practical look at one GIS professional’s experience completing MIT’s Applied Data Science & AI Certificate program, including key takeaways, challenges, and thoughts on how AI may impact the geospatial industry. *->If you’d like to present or sponsor a future GeoDC Meetup, please complete this [form](https://forms.gle/QbAXPfrDnX12GGaS8).*

The way organizations build teams and the way professionals build careers is changing. Fractional, part-time, and project-based work is no longer a stopgap. It's becoming a deliberate strategy on both sides of the work equation; the "Portfolio Career" of the future is happening now. In this session, Stephanie Ranno draws on her work connecting experienced professionals with employers who are rethinking how they access talent. Whether you're a content strategist navigating a tough market and piecing together flexible engagements or an organization weighing whether a fractional hire could move the needle for a specific project, this session offers practical perspectives for both. We'll explore what's driving the shift toward flexible work arrangements, how to position yourself or structure your team to make the most of it, and what it actually takes to make fractional and part-time roles work well for everyone involved. **About Stephanie** Stephanie brings more than 20 years of experience in staffing and recruiting, helping organizations of all sizes and in all industries build high-performing teams.

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
