What I’m interested in

Data × ○○

Data × Design = Visual Analytics

Art and Science of Visual Analytics Episode 0_1
Art and Science of Visual Analytics Episode 0_2
Forms and Positions

Data × Marketing = Digital Marketing

Data science is a high affinity field with marketing.
Therefore, I am focusing on this topic as a theme that can be turned into marketing actions based on the knowledge I have gained.
Most recently, I have been engaged in the following activities related to digital marketing;

Data × Engineering × Education = IT Training for non-Engineer

Education is essential for Information Technology skill development.
I would like to see a society that invests costs in technology education.

Data × Business Efficiency = BPR(Business Process Reengineering)

There are facts that non-engineers are not effectively utilizing IT due to literacy barriers.
I use the power of data and technology to innovate inefficient operations and improve operational efficiency.

Reading

What do I want to do?

I want to utilize safely and securely with Data with high social contribution

I am thinking of;

Develop data-enabled human resources and Increase the market value of data personnel

I believe that data-literate human resources will change the future of business.
I want to increase the value of data-enabled jobs such as data scientists, data engineers, and data stewart to the same level as in the United States and Europe.

Data Human Resources Community

I participate in events in the data human resources community to expand my knowledge and network.
I am also a speaker when I have the opportunity.
