I've saved an old theme from extinction by sanitising its code, also made it responsive with Bootstrap and face-lifted its design. The old theme was already heavily modified and building a new one from scratch was not an option.
BulletProof's new theme is built on a responsive Magento 1.x boilerplate that I've created using Bootstrap, For this particular project, I led the frontend team that built the custom theme and wrote parts of the code.
I helped Bellroy's development team transition their fixed width theme to mobile-ready. I've implemented new responsive layouts for their main elements and pages and left them with know-how and a solid foundation to continue on.
