Justin Osagie

Software engineer. Builder. Always learning.

I build software at Citi during the day and ship my own products after hours. Things like CareerBrief and What's in that Bill?, tools I actually wanted to exist.

When I'm not coding, I'm reading, lifting, or figuring out how businesses work. I like building things that help people. I like learning how things tick. That's pretty much it.

Featured Work

What's in that Bill?

Civic Tech

Career Brief

AI Product

What I'm focused on now

Learning how to build software that grows with your needs and keeps working over time. When I build something, I want it to work well today and years from now.

Building CareerBrief to help people prepare smarter and faster for interviews. I'm taking what I'm learning and turning it into something that helps others.
