I'm a software engineer with 8+ years of work experience in application development.

In the past 6 years, I’ve been writing Swift and made 10+ native iOS apps from scratch for clients.

At the moment, I’m working as a freelance engineer and focusing on two things:

  1. Helping client projects by utilizing my iOS/Swift skills and experience
  2. Exploring new languages and platforms for my future work

My technical interests include Functional Programming, Interactive UI development, and various tools that support software development. I’ve given many presentations about these topics, the slides of which you can find at my SpeakerDeck. There are some experimental projects and codes on my GitHub as well. Also, I enjoy doing pair-programming and using scrum/agile methodologies when working in a team.

Apart from professional experiences, I have interests in interdisciplinary fields of technology and society. This relates to my Master’s degree in Interdisciplinary Information Studies at The University of Tokyo in 2013. I’m trying to start working in these fields again.

I’m originally from Japan, moved to Prague in 2019 to have experience of working in an international environment, then moved to Amsterdam in 2020 to work as a freelancer. These moves are motivated by my ambition to contribute to software development culture.

Besides work, I like listening to the radio, thinking about philosophical things, visiting art exhibitions, reading books, and so on.

If you are interested in my work experiences more, please read my CV or LinkedIn. I can also show you my portfolio by request. Please contact me about it.

I’m looking forward to hearing from you about projects that I can help with!
