ABOUT ME
Data Scientist at UN Development Programme | Researcher
Data Scientist at UN Development Programme | Researcher

I am Bachelor and Master Candidate at Universidade de São Paulo (USP), based in Brazil, with 5+ years of experience in technology careers with data driven projects and 3+ years of work as a Business Intelligence and Data Science Analyst, participating as Data Engineer, Data Analyst and Tech Lead in several projects, recently more focused in the Public Sector.
Currently, I am enrolled in a Master Degree research focused in football analytics, with focus on maximization of expected goals through match events of a team.
The main goal of my career is to allow technology to promote evolutions in other knowledge areas.
I truly believe mentoring is a way to spread my knowledge and enhance opportunities for programmers who might be stuck in several questions: coding, networking, portfolio and carrer development.
