Hi, I'm Adam

I'm the the designer, developer, and problem-solver behind SimpliDev. With a background in maths from Oxford and a passion for technology, I build fast, clean, custom websites that help businesses grow online.

Taking a hands-on, personalised approach, I work closely with every client to turn your brand into a digital experience that not only looks great but performs brilliantly, without adding to your to-do list.

Every site is hand-coded from the ground up, tailored to your specific goals, and built to last, so you can focus on running your business. SimpliDev exists to make the web work better for busy businesses, one project at a time.
