I am lead developer of packages inside the JuliaSmoothOptimizers organization. These packages are focused on the development of optimization methods for nonlinear optimization.

Some of our main packages:


I am co-founder of CiDAMO, a Data Science, Machine Learning, and Optimization study and research group inside the Federal University of Paraná in Brazil.

We advise students and stimulate discussions about these topics weekly. We have monthly meetups (online) with guest speakers. Check the website for more information.

We have also created one of the first data science events on the university, with 8 companies and several participants, called CiDWeek, early 2020.
