I am well-versed in Python, SQL, Tableau (certified), Looker, Excel, R, SAS, and Spark. I am seasoned with data modeling, ETL, data visualization, data analytics, A/B testing, EDA, machine learning, and data mining. I believe that data confess numerous and amazing facts, once I take care of them with love and passion. I feel like reading Mother Goose or Brüder Grimm's fairy tales, when I uncover compelling stories from data. This process makes me empathetic to the customers behind the data.I am a people person as my military background explains. I love different cultures and languages. I want to be like my grandfather who speaks seven languages and lives with his motto: 2 M's aka Messiah and Mathematics.Let's make the world a better place with data analytics.========================================A snapshot of how data work in the Bible. (BTW, I think data are plural.)Don’t store up treasures here on earth, where moths eat them and rust destroys them, and where thieves break in and steal. Store your treasures in heaven, where moths and rust cannot destroy, and thieves do not break in and steal.Matthew 6:19-20I think that is why human beings created a cloud to store data. It is on earth, but a little bit more closer to heaven. Data are precious.
