About Cassie

I help UK businesses optimise their HR technology and processes, so they can focus on their people—not the paperwork. With extensive experience as an HR Systems Lead, I specialise in HRIS implementation, payroll audits, and vendor management, delivering measurable results in efficiency, compliance, and employee experience.

Whether you’re looking to streamline your HR systems, audit payroll and pensions, or navigate complex HR technology projects, I bring both strategic insight and hands-on expertise. I’ve successfully led HRIS projects from system selection to full implementation, negotiated contracts with vendors to secure better value, and designed processes that save time and reduce errors.

What I can do for you:

Optimise your HRIS and payroll systems for accuracy and efficiency

Conduct thorough payroll and pension audits

Lead HR technology projects from strategy to execution

Negotiate vendor contracts to maximise cost-effectiveness

Implement process improvements and automation

Provide change management support and staff training

If you want a trusted HR technology partner who combines technical skill, strategic insight, and a people-centred approach, let’s talk. I deliver solutions that work for your business and your team, not just “one-size-fits-all” fixes.
