Septian Ganendra S. K. (sepTN)
Indonesian software engineer, game developer, and Japanese language educator. I make games, build language tools, and contribute to open source.

Most of what I do falls into three buckets: game development, Japanese language tooling, and open-source contributions. The bigger public stuff is Jepang.org, Yomi, Sentou Gakuen: Revival, and a handful of small tools and datasets I keep offline-friendly and fast.
