Very smooth process, Rafael was very attentive and went above and beyond for me. He helped me make sense of a dataset that was very overwhelming and has been very supportive and honest with any follow up questions I have had. I would definitely recommend Rafael for any project and would be more than happy to trust him with any future projects :)

Rafael is truly exceptional. He understood my project completely simply from reading the overview I sent him. His report was extremely clear. He is also quite supportive and open to revising things to meet the client's needs.
