I am a committer of Apache Arrow, a member of Ruby core team, and a member of Red Data Tools project.
I'm focusing on to make Ruby a programming language that can be used for any tasks of data processing.
I'm working for tools and libraries below:
- Apache Arrow
- mainly SparseTensor in C++ API, C GLib API, and Red Arrow (Ruby API)
- pycall.rb
- Charty
- enumerable-statistics
- bigdecimal
- Ruby
- etc.
I love coffee so much. I often brew coffee weekend.
Also, I'm a hobbyist photographer. My favorite camera is Leica Q2.
