Open Source Software

I ❤️ OSS. Some projects I have been involved in:


Now superseded by GitHub’s own app, GitHawk was an iOS app that made managing GitHub accounts and projects easier. I worked on improving accessibility, writing blog posts and developing new features.


Moya is a network abstraction layer written in Swift. I contributed to this project by improving their documentation, migration from Swift 2 to 3, as well as providing technical support for developers.
