Hi! I'm Joseph
I recently founded yellow sunflower, an organization offering data consulting services and developing open-source tools for data scientists.
Most of my consulting work focuses on making data workflows simpler, more reproducible, and visually clean, from analysis to reports.
My core tools are Python/R for data work, Typst to create high-quality PDFs, and HTML/CSS/JS for web reports. I primarily work with clients in France (where I live!) and the United States. Feel free to send a message if you're interested!
Most of my open-source work focuses on data visualization and Typst. I've developed and maintain multiple Python/R packages and made tons of contributions to the Python Graph Gallery and the R Graph Gallery.
Sometimes I try to contribute to other projects too!
I do some other things, such as YouTube videos, TidyTuesday challenges, and talks.
Before working for my own company, I did internships at CIERI (research center), Wanteeed (e-commerce platform), and Dataviz Universe (Yan Holtz's company).
I also hold a bachelor's degree in economics and a master's degree in applied mathematics and statistics, both from the University of Bordeaux.
