About
I'm a product designer and engineer based in sunny Norfolk, England. For the past decade, I have taken products from 0–1, both as a co-founder (GetAgent.co.uk, Making Jam, LeadPro – exited in 2021) and consultant or partner.
My expertise spans application design and development, websites, design systems, branding, and marketing collateral. Depending on the project, I can take on the entire process—from design to implementation—or focus on specific areas while collaborating with existing teams.
