Tasked with bringing data science into Avanade Brazil, working on various problems for different clients. This work included fraud modelling using deep learning & h2o, sentiment analysis, audio analysis, BI, data visualization and data tidying. I gave a course on tidy data and several tutorials on the R language to staff across the company.

Headed a team responsible for making accurate forecasts of data on public spending. A big part of my job was also modernizing the way the department does analysis. To do that, I gave an in-house R course and built a Shiny application for the department (part of an internal R package that I wrote), along with the production of semi-automated reports.
