Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less.

me

Hello! I'm Sara Malvar, an electrical enginner with a master degree and a PhD in engineering. I've started my career at IBM and now I'm a postodoctoral fellow at the Research Center for Gas Innovation. I've also worked as a professor for Mechanical and Electrical Enginnering students and I'm now a machine learning mentor, reviewer and instructor at Udacity, Alura and Awari. It's always gratifying to help and teach people as well as partaking in a rabbit hole with students because everyone asks different qestions that would never occur to me.

I'm always looking for new projects, so feel free to browse the projects section to check out what I've built. If you want to work with me, want a mentorship or consulting shoot me an email at malvar.sara@usp.br or connect on linkedIn.
