Halliday.

Over the last 25 years I've taken health technology from idea to national scale. In 2012 I co-founded knowmalaria, a clinical decision-support platform for travel vaccinations and antimalarials. By 2018 it was running across Boots pharmacies in the UK, and we sold the business that year. During COVID I co-founded a testing platform that processed millions of tests, integrating with some of the UK's largest laboratories in a matter of days.

I'm a technology and product leader, not a hands-on engineer. I set the direction, help choose the architecture, build and lead the teams, and own delivery and governance. The part most clinical software gets wrong isn't the code, it's the thousands of decisions underneath it, and the clinical safety, security and governance that have to be right before anything goes live. That's the part I care about most.

Today I co-found and lead technology at Personalised Diagnostics, a health-tech group spanning human diagnostics, cancer screening and veterinary health, and at Pinpoint Travel Health. I'm also a non-executive director at Procyon Diagnostics, which is developing a pancreatic cancer screening test.

My deepest experience is in regulated digital health, but the same approach travels to any complex, regulated or data-sensitive software: governed, lean, and built to ship.

I write here about building technology in regulated, high-stakes environments.
