I started in computing by studying and developing low-level embedded systems, which has opened the door to the universe of Linux, networks, and other infrastructure topics. Then I worked on designing on-premises cloud infrastructure for some university laboratories and social organizations. These opportunities led me to engage in several open-source communities all over the world. At the same time, through social initiatives aimed at improving democratic processes in Brazil, I participated in the development of machine learning projects and clustering systems. In the last years, I worked for the gaming industry as SRE, building and maintaining solutions that support millions of daily active users worldwide. Now, I’m building a whole data infrastructure from scratch in a Brazilian startup.

Projects
Bigbang
Wildlife's tool for creating and managing global multi-cluster production environments with Kubernetes. I worked as the architect and the main developer, using technologies such as Golang, k8s client-go, Kops, Terraform, Vault, Etcd, AWS EKS, Helm and Gitlab-CI.
Ixu
A Prometheus exporter for Gitlab management metadata. I worked as the architect and the main developer using technologies such as Prometheus, Grafana, Python, Openmetrics and Gitlab API.
Pushing Together
A social platform for opinion gathering with checks and balances of opinion bubbles and manipulation. I was responsible for the clustering models using algorithms such as k-Means and PCA. I worked on its infrastructure, metrics collection, profiling and testing. The main technologies involved was Python, Numpy, Scikit-learn, Pandas and Matplotlib.
Pascalina
Personal project that aims at teaching computer science to women from other areas of science based on study methods of competitive programming. I'm one of the coordinators and the main teacher.
