Thanks for checking out my work. You can always head back home if you want!

I am a full-stack Ruby on Rails engineer with over three years of industry experience and a 2.1 degree in Computer Science at the University of Sheffield. I am a maintainer on GitHub's ViewComponent project and have used Hotwire (Turbo & Stimulus) since its release in December 2020.

Education, open source software, and making a positive difference all motivate me to do what I do best. Through these things, I aim to enable myself and others to change the world for the better.

Work in Open Source

While I was at, I contributed to open source regularly to improve dependencies, and maintained internal libraries. I also extracted code from to create projects such as nvar and remote_record.

I help to maintain ViewComponent alongside other developers inside and outside GitHub. I aim to support other ViewComponent users quickly and efficiently, and I am regularly consulted on its use internally at FreeAgent. I have also contributed code to Rails, Grouparoo, and ruby-jwt.

I want to make an ongoing effort throughout my career to support the tools and communities that enable me to make a difference.
