I’m an app developer and startup co-founder with a big interest in education technology and computing education.

I am also a primary school teacher and chair of governors.

App Developer

I have been building mobile apps since 2008 and can design & build for iOS, Android and the web. Some apps have been very simple one page apps, others have been very large or complex projects using cutting edge tech such as augmented reality and machine learning.

I have built apps within education, games and social media for clients from multi-nationals to startups.
