When she is not working as a software engineer at Capgemini, she uses her web development skills to remove micro plastic in the waters of the world. Her goal in this life is to work towards a more sustainable way of life, meaning that her hobbies include sailing the world, documenting underwater micro-life, and picking up trash with podcasts blasting. She is always trying on many different hats: trainer, team lead, community builder, talker, organizer. But the hat that fits best is developer.
