Hii, I’m Sii Cockerill

I’ve been designing and developing websites and web applications for over 25 years.

I’ve marked-up, styled and constructed websites using HTML, CSS, PHP, Javascript and MySQL. I’ve learned more than I ever thought I could, and yet somehow, I still manage to learn something new every day.

It’s now 2024 and I design websites and applications in Figma, and build them in WordPress using custom-built Block themes and plugins. WordPress is still my web platform of choice because it is so customisable and all of my clients have found it incredibly easy to work with.

Before I started Design Twelve, I experienced life in two different agencies; a pharmaceuticals communications agency and a very successful internet marketing / lead-generation company.

Both experiences were great and I learned a tonne about digital marketing as a whole, as well as running businesses online.

For the past 12 years, I’ve been using the expertise I’ve gathered to support businesses like yours — and I continue to love it.
