Hello, I'm André. I'm currently pursuing a Ph.D. in Computer Science at the Institute of Computing (Unicamp). I also have a master's degree (Unicamp) and a bachelor's degree in Computer Science (Unesp), a post-graduation in Web Consulting (Fatec), and a Technical Course in Computer Programming (Etec).

From the professional perspective view, I've been working and "playing around" with different programming languages since I was 15 (13 years ago). Through this period I developed several Web Projects at GBD database research lab (8 years ago), took part in the development of a financial control system for companies at Nash Consultoria Empresarial (6 years), and, with a team, developed 30+ e-commerce platforms for mid-scale companies at Cammino (3 years). Now I'm focusing on building Semantic Web and Machine Learning solutions to assist Brazilian e-commerce customers on their purchase experience.

Presentation

Undergraduate Thesis

The presentation of the project entitled "Text Mining in Big Data: Performance Optimization in the Extraction of Radicals in Portuguese Language Words" aimed to comprehensively illustrate the state of the art of Text Mining, what is the impact in Big Data and how one of the stages of this Mining - called Radicalization - can have its performance improved through the use of the Map Reduce programming model and framework.

Introducing Bitcoin

Workshop presented at Cammino Digital, explaining to employees and broadcast live on Facebook, which aimed to present the Bitcoin digital currency, its technological and economic impact on a global scale, Blockchain, as well as the entire ecosystem that was created in over the "currency of the future".

The Workshop lasted approximately 1 hour and was responsible for my immersion and deepening in a subject of such relevance today.

...
E-commerce Frauds

This workshop, also held on Cammino Digital's "headquarters" and broadcast live on Facebook, aimed to address the types of fraud most present in Brazilian e-commerce, taking into account that in most cases, who ends up in the loss is the shopkeeper.

Succinctly, ways to stop the act were discussed, both on the side of the shopkeeper, the customer, and the e-commerce platform.

...
Round-table Discussion

The round table became a tradition in the last Computing Weeks at Unesp in Rio Preto. By inviting former students who are in the job market or who have followed an academic life, the round table generates interesting discussions for the public, most of whom are undergraduate students from the Computer Science Course at Unesp, since most of these students do not contemplate what to do after graduation.

I had the honor of being one of the guests at such an event in which, after participating as a listener, organizer, I had the honor of becoming a member of the discussion table.

...
CCES Presentation
