Portrait of Fortune Zviregei

Hello, I'm

Fortune Zviregei.

Software engineer

I like software that stays legible once the excitement fades.

I ship full-stack web work: frontends users actually enjoy, backends that behave under load, and the habits in between that keep releases calm. Give me ambiguity, brittle pages, or a patchwork stack and I'm happy tightening it until the next increment feels ordinary.
