Résumé

01.About

Hello! My name is Mathilde and I enjoy making software, from concept to deployment. In my free time, I am really into knitting and sewing my own clothes, but this portfolio is all about tech!

I’ve had the privilege of working at a start-up specialized in NLP and a huge corporation. My main focus now is helping researchers at a neuroscience institute by providing them tools to collect and analyze data.
