Osajere Finney Software developer.

I build digital products, from concept ideas to implementation.

02About

Meet Finney.

Hi, I’m Finney, a software developer. At TradeByBartr (opens in a new tab) I help build a live digital trading platform from the ground up. Since 2023 I’ve also worked on community products, booking systems, commerce and media for clients and teams.

I bring a practical, end-to-end mindset: understanding the problem, implementing the feature, debugging, refining the experience and getting the product ready for release.
