Data Scientist

2018 - 2020
Avanade
  • Optimized internal processes of an automotive company, in order to build data-driven insights from vehicle sensor data. In particular, I reduced ETL and forecast time from 12 down to 1.5 hours, which led to eight times faster implementation.
  • Provided in-depth analysis and created an ad-hoc tool to monitor quantitative team KPIs and trigger forecasting models for a utility company.
  • Performed exploratory data analysis, hypothesis testing, data preparation and preprocess for statistical and machine learning modeling. I also assisted in architecture migration to big data solutions, premise to cloud, in a telco company.

Deczoo

https://fbruzzesi.github.io/deczoo/
Deczoo is a small Python library, a zoo for decorators. I developed and currently maintain the library.

There are many great decorators that I found myself implementing over and over in different projects. The hope is to gather them and use this codebase.

Tabular Data Annotator Web App

Data Annotator is an open source web app for annotating tabular data from a CSV file. It was originally intended for time series data, hence the repo's name and URL name.

It exists because countless times a business expert or myself had to annotate tabular data and this solution made it faster.

Tennis Stats Web App

Tennis Stats is a web app providing tennis analytics and insights in a more colorful and intuitive manner with respect to the official ATP Tour website. It uses open source data from the amazing Jeff Sackmann GitHub repository.
