March Meetup is here! Let's gooo! We have some amazing speakers, and of course pizza and drinks will be available after the event. ────────── **18:30: Welcome** Grab a drink, and a seat until everybody arrives! **18:45 Intro by Host Neciu Dan** **19:00 Kibble: Designing Hybrid Components for Native and Web** Speaker: [Traian Stanciu](https://www.linkedin.com/in/traian-stanciu/) Senior Software Engineer at Rover.com Building a component library that runs on web, React Native, iOS, and Android without diverging into chaos is harder than it sounds. This talk digs into how Kibble—Rover's design system—handles the gap between platforms through a file-naming convention (`.tsx` / `.native.tsx` / `.common.ts`), a unified event abstraction that bridges web click and native press events, and a token pipeline that generates Swift, XML, CSS, and TypeScript from a single source of truth **19:25 React Native in a Native App: Brownfield Integration & Over-The-Air Deployments** Speaker: [Luca Barone](https://www.linkedin.com/in/lucabarone95/) Mobile Engineer at Rover.com A practical look at how Rover.com ships React Native screens inside fully native iOS and Android apps — without rewriting them from scratch. We'll cover the "brownfield" integration pattern, how JS and native code communicate through bridge modules, and how we deploy JavaScript updates to users in minutes using Expo EAS Update, completely bypassing the App Store review cycle. **19:50: Drinks and networking!** Do you want to talk at this meetup? Reach out to Dan Neciu [on LinkedIn](https://www.linkedin.com/in/neciudan/) And please help us spread the news and grow the community: **20:55 Meetup finished** **Disclaimer** **This event is intended for the exchange of knowledge and ideas among participants.

**Parece que ya no se pueda hacer nada sin pasar por la IA, pero si se usa como una herramienta más, permite acelerar radicalmente el desarrollo, desde el prototipado hasta el lanzamiento de webs funcionales sin necesidad de escribir todo el código a mano. En esta ocasió, veremos 10web y su nueva herramienta de Vibe for WordPress, que permite crear un WordPress con toda su infraestructura sólo con unos pocos prompts.** 10Web integra herramientas de generación AI-nativa, hosting gestionado, optimización automática y un builder basado en Elementor enriquecido con widgets profesionales, todo ello en una única plataforma. Este sistema de vibe coding permite pasar de textos descriptivos a webs completas en muy poco tiempo, combinando libre creatividad frontend con todo el backend potente de WordPress: plugins, WooCommerce, SEO, gestión de usuarios y mucho más. Este enfoque no sólo reduce drásticamente el tiempo de desarrollo, sino que democratiza el acceso a la creación web, haciendo posible que desarrolladores, agencias y creadores autonomicen proyectos con alta calidad técnica en cuestión de horas. ¿Quieres ver un nuevo enfoque de la IA para WordPress? Apúntate y ven a aprender con nosotros.

Meeting Room 2b, Main Library Join us for a welcoming evening of reflection, gentle music, and meaningful conversation. We’ll begin with a short grounding moment, followed by a brief reading from spiritual or philosophical traditions, and an open reflection circle where participants can share (or simply listen). Libera Animae is an interfaith community focused on inner growth, creativity, and authentic connection. We desirere to cultivate a space where all questions are welcome and all members are treated with compassion and respect. All backgrounds are welcome.

**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 **Abstract** Web Forms gave .NET developers a powerful abstraction for building reusable UI controls long before design systems were a thing. Web Components finally bring that same idea to the browser natively. This session explores how the Web Forms mindset translates into Custom Elements, Shadow DOM, and HTML templates. We’ll examine how Web Components enable design systems that work across frameworks, how they differ from server‑driven controls, and why they’re becoming a foundational layer for modern UI. Whether you’re maintaining legacy apps or building greenfield projects, you’ll leave with a practical understanding of how to apply familiar patterns in a modern, standards‑based way. **YouTube Link** TBA
