Experienced Research and Development Engineer, addict to Web Technologies, I have had 20+ years of experience in the design and development of advanced Web applications.

Specialized in Web technologies and modern JavaScript, I work to make the best use of them on platforms where they are available: desktops, mobiles, tablets, embedded systems...

Being software craftsmanship oriented, my concern is to deliver well-defined, reliable and scalable applications. My development environment includes automated tests and continuous integration platforms.

My areas of interest currently revolve around JavaScript technologies like TypeScript, ES6, Svelte, SvelteKit, MobX/Mobx-Keystone, Rust / WebAssembly, ReactJS, Redux, etc; as well as the audiovisual, 3D, virtual/augmented reality and IoT (Internet of Things) sectors.
