Leon Sólon S.

As a data scientist with 6+ years of experience working with Python, I am proud to have earned 10th place in the MeLi Data Challenge 2021. In addition to this achievement, I have designed, built, deployed, and monitored predictive models still in production. Additionally, I have used deep learning to design fraud detection systems for proctoring. My experience extends beyond just building models, as I also host a data science channel and podcast (Let's Data) where I share my knowledge through machine learning teaching videos. I have been freelancing for a long time and have worked with clients from all over the globe. Through platforms like Upwork and Codementor (where I have done 64 jobs/sessions and 25 reviews, all five stars - check [login to view URL]), I have honed my skills and become adept at collaborating with remote teams to deliver high-quality work. Main skills: - Languages: Python, SQL, R, Java - Frameworks/Libs: Pandas, Scikit-Learn, PyTorch, Plotly, Seaborn, Matplotlib, Flask, Django Client reviews from Codementor: Sam Bravo - November 2020 Leon was the best help I have ever received.
