I'm an engineer. I [build things](https://fdarian.com/software) when I see something that could be better.  
I think a lot about abstraction, philosophy, and [music](https://music.apple.com/profile/fdarian).

Currently I work on agents at Risedle. I also advise [atur.ai](https://atur.ai) and [artistlive.id](https://artistlive.id), both of which I started as technical founder.
