Rust type system

rust-lang/a-mir-formalityOutreachy internship · Mar – Aug 2026

First-time contributor to subsystem owner in five months, in the formal model of the Rust type system, under mentorship from Niko Matsakis.

Status updates with Niko on Zulip. When a PR of mine was sitting in review I would go pick something else off the issue tracker rather than wait. In office hours I mostly listened and watched the big dogs cook. He reviewed my code live a few times, thorough and relaxed at once, which I did not know was a combination. It made open source fun instead of intimidating.

About

Background

I build the dense end of the frontend: dashboards, admin panels, pipelines that update while you are looking at them. That has been payments at Finaract, CRM at Mass Axis, trading, and e-commerce I ran end to end. Four years of it remote, from Abuja.

Off the clock

Not work

Do you like music?
One of the best things to ever bless humanity. Afrobeats, pop, rap, you name it. My favourite is Juice WRLD, because he is versatile and he just hits my eardrums right.
What do you think about anime?
Great, and I am glad I started before the great shift. IYKYK. Naruto was the first one I heard of and it hooked me back in 2017, but Attack on Titan was the first I actually watched, and it did not disappoint.
What are you currently bad at?
Badminton. Right now it plays out as a humiliation ritual on the court (I smashed on my own partner), but one day I am going to surpass my limits.
