Three tech areas I'm going into

Since the beginning of 2021, I’ve been considering tech areas that I’m going into for the next few years. As I roughly decided them, let me share my thoughts about it :) Context Back in 2015, I decided to focus on iOS app development, since when I’ve been working mostly on iOS apps. To keep being a good iOS developer, I had to keep up with so many topics around Swift/iOS and wasn’t able to make enough time to catch up with things outside of them....

My past presentations

Let me share my past presentation slides. Even though some engineers in Japan know me because of my past talks, those who aren’t familiar with the Japanese dev community might not know me well. Giving presentations is an important activity for me. I like summarizing my interests, knowledge, and experience into the format of presentations from time to time. Therefore, I believe these presentations have represented my interests quite well....

Haskell and Swift

Hello, world. Let me share some of my findings of Haskell and Swift. I got interested in functional programming, especially in Haskell, when I realized that most of my favorite Swift features come from functional programming. My favorite features include enum with associated values, Result type, higher-order functions (i.e. passing functions themselves), KeyPath type, and so on. After started learning Haskell, I found there are more common features between Swift and Haskell than I expected....

Learning Again, Nov 2020-Mar 2021

While preparing for my new life and business in a new place, which is in Amsterdam, the Netherlands, since November 2020, I used a lot of time to learn new things. Since 2015, when I started working on iOS app development, I’ve focused on iOS/Swift things and haven’t spent much time learning outside of the iOS/Swift world. This was a strategic choice and I learned a lot by exploring Swift. However, I felt the time has come to learn outside of iOS/Swift, to have broader and deeper knowledge about software development....
