I’m an experienced Electronic Engineer focused on Mixed-Signal Electronics, Embedded Systems and the Internet of Things (IoT).
Over the last 15 years, I’ve worked for a number of the world’s leading semiconductor companies. I now share my design skills and industry knowledge with clients wishing to design, manufacture and ship high quality, innovative products.
I run Mixed Signal Systems Limited from Edinburgh, Scotland – a vibrant city, ideally located to support clients in Europe and North America.
In hiring me, you will benefit from the experience, expertise and enthusiasm that I bring to every project.
Please contact me if you’d like to discuss how I can help bring your product to market, resolve existing product issues or provide relevant industry insights.
