Over 20 years experience across accounting and finance — with deep expertise in compliance, enterprise systems, process improvement and building teams. ACCA qualified.

I'm building Calceum because two concerns keep coming up in conversations with practice owners. How do you leverage AI in the way a practice actually operates? And how do you take on the incoming wave of MTD for Income Tax clients without trading away the time your team should be spending on advisory and growth? Calceum is a practice management platform being built for both.
