Hello, I’m Callum

I led the end-to-end UX/UI evolution of the Ware platform, ensuring it was not just visually updated, but also functionally improved to better serve HR professionals and employees. My role involved redesigning core HR workflows, enhancing usability, and building a scalable design system to support long-term growth.

Helping users take control of their energy. By providing real-time solar and home energy tracking, this feature led to an 85% improvement in user satisfaction and a 20% reduction in support calls, empowering homeowners with clearer, more actionable insights.

I led the end-to-end design of the Sero Life app, enabling users to manage heating schedules, control smart home devices, and optimise their home’s energy efficiency. This intuitive solution gave users greater visibility and control, with 70% of users reporting improved confidence in managing their home energy

I led the redesign of the Installer App, streamlining the process for engineers installing the Building Environment Engine (BEE) in customers’ homes. By reducing unnecessary steps and improving UI efficiency, we cut installation time from 50 minutes to 15 minutes, with 70% of installers reporting a faster, more efficient workflow.

I led the end-to-end design of an internal web app for Sero Engineers and the CX team to remotely monitor and manage home energy systems, reducing the need for onsite visits. This solution streamlined troubleshooting, improved response times, and enhanced operational efficiency, allowing teams to support customers without being physically present.
