Portfolio

Guessb: a tool for detecting offensive comments upon Facebook user's data.

A tool for detecting offensive comments writed in brazilian portuguese upon Facebook. The tool can label comments in three classes: positive, negative or neuter. To do so I've built an engine using Natural Language Toolkit (NLKT), combined with Multinimial Naïve Bayes algorithm available at scikit-learn library and to do the training I used a huge amount of manually labeled text corpora.

koala-games (owner): it's an open-source game development organization

I created this organization a few months aiming to provide an open-source game, and to spread the knowledge that I'd be conquering doing that. To do so, the organization's collaborator intend to build an open-source single-player, single-scroller PC game upon Unit 3D engine. Until now, we have a team composed by 5 member, but we aiming to increase it.
