The person who created this course

In the early 2000s, I started working in the data field. I first began with tasks involving extracting and loading data using SQL. Back then, watching my senior colleagues doing modeling, I made a resolution thinking, 'I should become a modeler someday too.'

Through long experience with data and continuous study, I not only became a data modeler but also developed data analysis capabilities to become a big data analysis expert.

I've created this course based on my experiences for those who want to grow as data professionals. By taking this course, you'll be able to develop practical skills beyond just obtaining certifications.

I hope all the students will always be happy.
