Hiroshi Wayama

Hiroshi Wayama was born in Morioka City, Iwate Prefecture in 1983. Graduated from the Faculty of Science, Kyoto University, and the Graduate School of Science, Kyoto University. He joined a camera manufacturer in 2009. In 2009, he joined a camera manufacturer, where he was engaged in semiconductor process development, numerical calculation, simulation technology development, and cloud-based web application development. In 2019, he left the company and became independent. In 2019, he left the company and started his own business. Currently, he is working as a machine learning engineer in charge of several machine learning projects. His current interest is recommendation systems.

Skill Map

This is a visualization of my past experiences.

The hierarchy of each item is not equal. I wrote this as I thought of it, so it may be difficult to read.

I’m only half joking when I say “mahjong”, but I’ve been playing mahjong since high school and after high school, and there was a time when I really thought I would make a living at it. I had been playing mahjong since junior high school, so I had a little confidence in my skills. Now, I have given up the idea of going into that field because I can’t keep up with my physical and mental strength, but I was always playing mahjong, whether I was asleep or awake. I remember playing 24-hour endurance mahjong during the year-end and New Year holidays and going to a mahjong parlor on Christmas Eve, and when I came out of the parlor after playing all night, there was snow on the ground.

When I was a student, I learned physics, mathematics, self-taught C language, C++, Linux server, etc. When I was a salaried worker, I experienced semiconductor, numerical calculation, and system development. Looking back, I can see that all the technologies I have experienced are useful in my current work. Although I did not choose my technologies with this in mind at the time, I am glad that I have continued to make efforts at each point in my life.

My conclusion is that hard work rarely pays off, but if I hadn’t made the effort in the past, I don’t think it would have been possible to live independently. I am satisfied with my current work, which is challenging, fun, fulfilling, and gives me a good income, and if I think about it, my efforts may be somewhat rewarded.

I still have about 40 years left in my life, so I am looking forward to seeing how things will change in the future. I will update this page about once a year.
