About

Founder of Speeku (https://www.speeku.com), a gamified language app for the languages and varieties the big apps skip: European Portuguese, Swiss German and more. Fun, bite-sized lessons, every word spoken aloud and a full dictionary behind it. One-time payment, fully offline: everything runs on the phone. I build it end to end, from the React Native app to on-device speech checking. Based in Zurich.

Speeku is a gamified app for European Portuguese: the Portuguese of Portugal, not Brazil, from the very first lesson. Nearly 1,000 bite-sized lessons from A1 to B1, over 11,000 exercises of more than 50 kinds, every word and sentence spoken in European Portuguese, and a 7,000-entry dictionary with full verb tables. One-time payment. Fully offline: no ads, no subscription, and the app doesn't even ask for permission to use the internet.
