Bonjour Hi! I am a former electrical and software engineer from Québec City, Canada, living in Seattle since 2005. From my time working in quality assurance for voice recognition software, I care deeply about science, problem solving, and being practical. I also come from a long line of seamstresses, having learned how to sew from my mother, grandmother, and aunts. When COVID-19 hit in March, I merged my interest for science, my technical background, and my knowledge of sewing in order to create comfortable and safe masks for my family and friends. I constantly stay informed about the latest safety guidelines and strive to create the highest quality product for the people I care about!
