This post is a report of my activities in Q2, 2022. While working on client projects, I started learning Information Visualization. I hope this will give me new skills and lead to outcomes in the near future. Client work An app project with a startup Building a new messaging app for teenagers. Switched to tech-consulting work in June Making some features while sharing programming techniques Art app projects with an artist based in New York Technical consultancy work: giving technical advice and writing code together in pair-programming sessions using TUPLE. In-App purchases, image processing, Firestore migration, etc. Learning Information Visualization specialization at Coursera I learned the foundation of information visualization and the basics of D3.js. I’m interested in visualizing complex data these days. My next step would be to visualize the complexity of programming itself. I hope I’ll be able to share the outcome in the near future. Elm + Tailwind + Firebase Hosting I tried making a website using Elm+TailwindCSS and hosted it at Firebase Hosting. The website is here. (The contents are copies of my website.) Dutch basics using Dualingo and some books Tech Events Unison Forall, 24 June Great conference about Unison programming language. Rust Developers Amsterdam meetup, 22 June I learned a little about Makepad, a GUI framework for Rust. CocoaHeads NL @Stream, 15 June Coffee coding, Saturdays Other stuff Visiting museums ...

This post is a report of my activities in Q1, 2022. Although there weren’t many changes, there was some progress, including web frontend development trials using Elm, TailwindCSS, and Firebase. Enjoy reading✨ Client work An app project with a startup Building a new messaging app for teenagers. Using SwiftUI, The Composable Architecture (TCA), Firebase, GraphQL, and so on. Using lots of features from Firebase. Art app projects with an artist based in New York Technical consultancy work: giving technical advice and writing code together in pair-programming sessions using TUPLE. Learning TailwindCSS + Elm I’m making a copy of this website using Tailwind and Elm. Tailwind seems great. Handling CSS had been one of the obstacles for me to get into web frontend development, however, with Tailwind I feel I can finally control the appearance of websites precisely. So, I may be able to work on web frontend projects. ...

Hello, world! It’s time to look back on 2021, isn’t it? 2021 was my first year as a freelance software engineer in the Netherlands, which was very dynamic and full of new experiences.

Hello, world. As Q3 of 2021 has finished, I wrote a summary of my activities during this period. The summer has finished, winter is coming very soon, but I’m enjoying nice autumn weather very much these days. I hope these activities in Q3 will lead to great outcomes in Q4 and the future.

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. ...

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. So, enjoy reading these. If you have any questions or maybe future opportunities for talks, I’d be more than happy to hear from you! ...

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. Some data types are essentially the same, some syntax is similar, and some concepts are common. In fact, Chris Lattner, who is the main author of Swift, confirms that Generics in Swift is inspired by Haskell according to an interview. ...

Hello, world. I’m going to share my report on the second quarter of 2021. Fortunately, I could start working on a client project, learned new stuff, and attended some events! I hope to see some more progress in Q3. By the way, in the Netherlands, April and May were quite cold😰 (April was the coldest April in 35 years in NL!), it became warm☀️ (almost suddenly) in June. Client work Coral app Apple/Google SignIn, Push Notification (FCM), some new screens, some investigations, and bug fixes. Thank you, Coral team! I’m open to working on more projects on a part-time basis or short-term projects. Contact me if you need my help! ...
