Roger Rovira

I’m a design engineer based in Barcelona, focused on building polished apps and websites. Currently working on passion projects while studying computer engineering at the Polytechnic University of Catalonia (UPC).

Most recently, I shipped a cross-platform mobile app for Medva and developed a privacy-preserving search application recognised by the Spanish National Research Council (CSIC).

I believe people can sense when products are built with care and intention. That’s why I obsess over every detail, both in design and code, to create solutions that are not only functional but also delightful to use.

Medva App

A mobile app for Medva, a door automation manufacturer, that enables field installers to perform motor installation calculations on site instead of referring to manuals.

I designed its design system in Figma and built the app with React Native and Expo, from guided multi-step forms to passwordless sign-in and haptic micro-interactions.

Solitude Search

A private search engine powered by homomorphic encryption, where queries are answered without the server ever seeing them. Recognised by the Spanish National Research Council (CSIC).

I brought the encrypted retrieval client to the browser with Rust and WebAssembly, designed the interface, and typeset the research article and poster.
