Background

About Giuliano Janson

My professional experiences has centered on advanced analytics and applied machine learning. In analytics I enjoy the process of bringing ideas to life. Most of what I do falls into three categories:Data Exploration: about 30% of what I do is gathering, re-shaping and exploring complex, dirty, large-scale data. Usually SQL, Hive, Spark to munge terabytes of data down to something I can analyze in Python, R or SAS.Machine Learning: most of my time today is spent on building machine learning solutions. From helping customers frame a problem to delivering production ready solutions, I touch all aspects of building impactful models. My favorite parts are feature engineering and thoughtful cross validation.Building Data Products: I use quantitative approaches to build and prototype solutions that add business value.My philosophy in analytics boils down to achieving the right mix of three key elements I believe each and every piece of analytics should be made of: analytical rigor (the "science"), creativity (the "art"), practicality (customer focus).I have enjoyed participating in Machine Learning competitions on Kaggle where I have earned Kaggle's highest status of GrandMaster (only 76 in the world). To date I've won two competition and I've been ranked as high as 12th out of data scientists from all over the world. Kaggle is not only fun but provides a great platform to get exposure to applied machine learning in various industries. To date I've tackled problems ranging from retail sales forecasting to social media natural language processing, from loan default prediction to identification of fraudulent activities on e-commerce websites. My winning model in the Avito competition (described below in my profile) is used to identify illegal content in more than 22 millions ads each day on the third largest classifieds website in the world.Geeky stuff aside, I enjoy long distance running and obstacle races. I started running marathons a couple of years ago and so far I've run 4 marathons and dozens of Spartan races.
