This article was translated from Japanese by Claude Code.
As the title suggests, I’m looking back on the first half of 2025.
Work#
Attended KotlinConf 2025#
- Took advantage of our location and attended with colleagues from work
- It was great being able to talk directly with people from JetBrains and Google and ask them questions
- For my colleague, it was their first conference attendance. After the event, they said “My perspective on conference participation has changed—it was so much fun and meaningful,” which made me happy
- Recordings are available here

Wrapped Up a Major Project#
- No major issues so far
- Beyond coding, I also worked on overall architecture design and had meetings with backend teams about response formats and other topics
- I was sharing technical knowledge with teammates while also house hunting (mentioned later), so I got shingles from being too busy. Health is important
Personal Life#
Traveled a Lot#
Places I visited in 2025:
- Antwerp, Belgium (accompanying my wife on her business trip)
- Malaga, Spain (vacation)
- Mijas, Spain (vacation)
- London, United Kingdom (accompanying my wife on her business trip)
- Copenhagen, Denmark (KotlinConf)


House Hunting#
- Haven’t moved in yet, but if everything goes smoothly, we should get it soon!
Temporarily Returned to Japan#
- Went back to Japan. Japanese food is divine. Met mainly with people from projects at my previous job. Was also able to see my wife’s family and my own family
- Asked a lot about AI, and it seems Japan is more advanced than our company in that regard. Japan is amazing. And Japanese food is divine
Other Notes ① - Miscellaneous#
- Come to think of it, the Happy New Year fireworks were amazing
- Amsterdam is actually perfect for cherry blossom viewing. Fewer people, you can relax and see the cherry blossoms up close

Other Notes ② - Home Cooking Photos from First Half of 2025#
I got into making desserts for a while. I’ll do it again.






Summary#
- Got hooked on Type Pro and wanted to become like Kikuchi or Hara-kun, so I’ve been gradually working out, but progress hasn’t been great. Health first!
