Pierre-Henry Soria. A passionate software AI engineer and polyglot who created JoraSpeaks because of his love for learning new languages! 🌍 French is his mother tongue. He started learning English when he moved to Manchester, UK, and since then has learned many other languages. This personal journey of language learning—experiencing the struggles, breakthroughs, and joy of connecting with different cultures—inspired him to build JoraSpeaks: an AI-powered app that makes language learning more accessible, effective, and enjoyable for everyone.
When not coding or learning languages, Pierre-Henry enjoys traveling around the world, photography, exploring AI innovations, continuous learning, and staying healthy! 😊 Find me at pH7.me 🚀
