Worked at the Identity Team. Responsible for implementing a new session manager system. The system is responsible for storing and updating session variables of every shopper at VTEX.

Arvore is a B2B SAAS company. Their product is similar to Netflix but for books. As an intern, was responsible for gathering and preprocessing data and later on building ML models. My last task was to improve the recommendation system of our books for users. I implemented a new approach using recommendations for bipartite graphs and spectral transformations of the adjacency matrix (Inspired by this thesis https://kola.opus.hbz-nrw.de/frontdoor/index/index/docId/581). Besides, I automatized our recommendation process by running it on Rundeck using bash scripts.
