My primary specialty is data visualization. I have worked in many institutions for 13 years and created many visualizations.
I teach Tableau Desktop for all levels at Udemy. I also work as a freelancer on Upwork in data visualization fields. Besides, I am a beta-tester on online learning platform Coursera. I do beta-testing the courses of top universities like Yale, Michigan, Stanford, and leading companies like Google and IBM before they launch their courses (in fields such as data science, machine learning, programming language courses).
