Navisu is a custom osu! server with a uniquely fast bancho/score submission implementation
and its own frontend, as well as a number of homebrew tools written for it.
It also hosts an active community and a dedicated staff team.
Beatconnect is a mirror for osu! which I mostly do UX and API development for.
Chloe.moe is my uploading service and CDN.
osu!monthly is a monthly magazine which I was the lead designer and web developer of.
Various other osu! projects (2017-2018)
