Daisuke Mori (Morry)
Software Engineer | Math Teacher
I have worked mainly in finance and business dev., and am currently working as a software engineer while teaching mathematics to junior high school students.

Motivation
I have gained business experience in various fields such as finance, business development, and software development, and now I teach mathematics to middle school students at a supplementary school overseas. Although my career path may seem unconventional at first glance, there has always been a strong passion for "learning" at its core.
In fact, I struggled with mathematics during my middle and high school years, and before I knew it, I had gravitated towards the humanities, majoring in English at Tokyo University of Foreign Studies and completing graduate school. When I revisited mathematics as an adult, I discovered an appeal that I had not noticed during my student years. Surprisingly, this appeal had much in common with my work in programming.
Both require logical thinking and step-by-step procedures. Just as "debugging" is crucial in programming, in mathematics, it's important to carefully rework problems you've gotten wrong and understand why you made mistakes. For instance, identifying whether it was a calculation error or a misunderstanding of a formula... pinpointing the cause allows you to deepen your understanding with certainty.
Moreover, mathematics is built upon a succession of units. If you don't understand the previous unit, it's difficult to grasp the next one. However, if you thoroughly understand each unit, even difficult problems become easy to solve. I realized the importance of steadily building understanding, much like stacking blocks.
When I started studying mathematics again after more than 20 years, I was surprised to find that textbooks and teaching methods hadn't changed much since my school days. While there are now many video learning materials available, I believe their content hasn't changed significantly from before.
On the other hand, I noticed that many convenient and easy-to-understand applications for smartphones and tablets have emerged. Using these apps should make learning mathematics more enjoyable and allow for deeper understanding. However, some of these apps can be difficult to use or require programming knowledge.
That's why I launched graphiq. At graphiq, we provide learning content that allows anyone to easily understand mathematics while utilizing the latest apps and tools.
Through graphiq, I want to convey the joy of mathematics and its connection to programming. I hope to be of help to students who struggle with math, those who want to learn more deeply, and the parents who support them.

Hobbies and Passions
Coding
I enjoy creating web apps that I want to make and learning new technologies in the process.
Walking
I think it is effective for refreshing the mind and body and improving concentration. I often take walks while thinking.
Cooking
I have liked cooking since I was young. However, I recently realized that I like it because it is similar to mathematics and programming, such as understanding the nature of ingredients, measuring seasonings, and the importance of cooking procedures.
