About

I care about clean data models, documented REST APIs, and code the next person can change safely.

Off the clock
Puroresu, Afrobeats and a controller. What I watch, play and listen to once the laptop closes.
On repeat
My girlfriend got me into Asake, and into most of this list: Afrobeats, 2000s pop and 90s rap. It all plays while I code.
