Back to original languageAbout Bill Olivier Junior
A statistician by training, I leverage my data analysis skills to help companies and organizations transform their data into actionable insights for decision-making.
I handle the entire data processing chain: collection, cleaning, statistical analysis, modeling, process automation, and dashboard creation. I use tools like Python, SAS, SQL, R, Power BI, and Excel to develop reliable solutions tailored to business needs.
My experience spans various sectors, including finance, the public sector, and consulting, where I have conducted statistical analyses, developed decision-support models, and automated data processing workflows.
Rigorous, autonomous, and results-oriented, I am seeking opportunities in statistics, data analysis, business intelligence, data science, or data automation.
