DDB EXPRESS
I’m a Freelance Software Developer from Perú based in Naples, Italy, focused on building fast, maintainable web and mobile applications without unnecessary complexity. I’ve worked across startups, consulting, and enterprise teams, contributing to products used in Italy, Spain, and the United States. My experience spans frontend, backend, infrastructure, deployment, and product delivery, with a strong focus on Flutter, Dart, Go, and lightweight full-stack systems.
Beyond client work, I actively build open-source tools around simplicity and developer experience, including HTML builders, HTMX helpers, and small experimental projects. I enjoy working close to product and business problems, turning technical decisions into practical solutions that help teams move faster and build better software.
Full-Stack Dart with HTMX
Lightning talk
What if you could build dynamic web interfaces in Dart without creating a separate frontend application, JSON API layer, client-side router, and state management system?
In this practical session, we will introduce htmx, a small library that lets HTML elements make HTTP requests and update parts of the page with server-rendered HTML. Instead of sending JSON to the browser and rebuilding the UI in JavaScript, the server returns HTML fragments directly.
We will see how this works with Dart by setting up simple routes, returning fragments, handling forms, updating lists, adding search/filter interactions, and structuring small server-driven components. We will also look at how Tailwind CSS and small complementary libraries can fit into this stack.
We will learn how htmx works, how Dart can return interactive HTML fragments, and when this approach can replace a heavier SPA architecture.
