2001
I released a shareware for teachers of Windows users in Japan when I was 13 years old. My journey has began.
2012
I released applications for iOS, Android.
2013 – 2018
I worked at NTT Solmare as one of the members of software engineer.
I developed games for iOS.
And I learned how to analyze data of user’s behavior with Machine Learning.(Python on Jupiter notebook)
I used natural language processing and supervised learning to classify user inquiries. This was done to reduce the burden on the person in charge. The person in charge spent a lot of time each month reviewing and categorizing the inquiries from many users of the game.
2018 – now
I have been working at a real estate company as a full-stack engineer.
I developed a system like phone-call and customer-management-system for my company by myself. （ubuntu on a server さくらサーバ, PHP, MySQL, javascript, asterisk and C# for native apps for it. Thank you for everyone online)
It works well, effectively. sales staff can call someone on a list with it automatically. I achieved 400%( I mean 200 -> 1000 par a person in a day) increasing the number of calls. And I analyzed the logs and got some insights then I was able to reduce the cost of them 80% down.
And , I migrated all Active Directory Windows Server that I had built on my company’s two on-premises server five years ago to AWS. Everything was fine up until the day of the migration, but shortly after the migration I discovered a problem. Although finally I luckly managed to fix it, the company’s network went down for 6 hours. I have almost no memory of that time because it was an extra 6 hours after I had already worked hard for about 30 hours. It’s my big failure 🙂
Finally, I launched two EC2 instances each with two different AWS accounts and connected them with an AWS Site-to-Site VPN. To reduce costs, the instances is automatically stopped at night and I added a trigger to bring them up at any given time. I achieved a cost reduction of about 30%.
These days I have been learning data analytics things with ML again and I got that kind of certificate provided from google. Thank you 🙂
