Hi there! I am Wesley 
,
I’m a computer engineer turned data scientist.
My biggest interest revolves around simplifying our day to day lives through technology and AI (even before the hype).
Besides that, winning a full scholarship for both high school and university has reassured me of how essential and life changing quality education is. Switching between first and second in class, I also focused on filling all the 24 hours a day has to fit all the extracurricular activities and homemade projects possible and give my best to honor those who believed in my potential.

At ISMART, Institution that provides scholarships for low income talented students I had the opportunity to study at one of the best high schools of Brasil, Colegio Marista Arquidiocesano, with 100% scholarship. As if it wasn't enough, there is still a personal development program that I'm still part of.
Back at BTG I was then responsible for building the entire infrastructure around the Credit/Collection data analysis suite. Everything from ETLs and dashboards to predictive modeling and scoring. - After a year and a half, I was promoted to the Advanced Analytics subdivision, being in charge of finding novel solutions to problems other analysts could not solve through ordinary means. At this position I built a complete graph analysis tool that could give the flexibility of graphs wihout the need to maintain a propper graph database, being mainly used for PLD and fraud detection purposes. - One more year has passed and I felt the need to dive completely into the core of the data-science world, officialy migrating to the data science team. More specifically to the Risk Squad, responsible for building credit scoring and fraud detection models.
With a full scholarship I joined Insper knowing I had to experience all I could. So I did it! I would spend all the time out of classes at the labs, trying all the tools and machines available, from oscilloscopes to 3D printers. When the time came to use them in class I could already help my classmates and try more advanced experiments. Out of classes and labs, I joined VEGA Cultural, a student-run organization focused on bringing cultural activities to the campus, in which I took care of the financial side of contracting and renting the installations. From the 2nd semester on to my graduation I have been constantly reelected as the class representative for the great relation I had built with all the Faculty and university's departments. All of that while making sure to say between 2nd and 1st in class.
Partial scholarship for the summer Program for Capstone Design Project. Aside for the the understanding of design, manufacturing and the applications of solar cells and 3D modeling, this program was my first experience outside of Brazil. It gave me the confirmation that as long as I am doing what I love, which is being an engineer surrounded by brilliant people, I will be happy wherever the country, language or currency.
At BigData I chose the challenge to validate and analyze a space state based time series forecasting model for use in scarce data scenarios without having ever studied time series forecasting. Diving through the papers and the code written I was able to implement other baseline methods for comparison while also getting a performance improvement of 40% in the prediction runtime and doubling the size of the proxy pool used by the whole company.
I started at BTG with the task to build an interactive dashboard for consolidating the risk and origin of incomplete financial operations. Finishing before the deadline, I was able to integrate the company's MQ service with the internal SQL database, giving the Operations area data they had never been able to get on time.
I joined Dolado as a javascript backend developer, implementing routes for the company's marketplace. The number of customers was increasing and during meetings we saw the need to better understand what was the experience we were giving them. I joined the senior developer two weeks after starting on my position. After two more weeks, with the results and ideas I brought I was assigned to the leadership role of the Data squad, building the infrastructure to gather, store and analyze all the user data needed to understand out customer.
