Hi, I'm Will.

I’m a product designer with experience in UX/UI, industrial design and design engineering. I care about building software grounded in truly holistic design, products which work effortlessly for the people using them whilst looking great.

For the last few years I’ve been working as the principal software designer at Midsummer, a mid-sized company, where I handle design direction, brand identity, and UX/UI strategy for all key projects.

Work

UX / UI Designer

Midsummer Energy, 2022 - 2025

Software design, focused primarily on the system design products Easy PV and Heatpunk. I built design structures, systems and practices from the ground up in a company that had never previously had a design team. During this time I led the creation of a unified design system to bring consistency, clarity and long-term maintainability to both products, working closely with engineering to ensure it could be implemented effectively. My role also involved carrying out user research, including installer interviews and internal workshops, to understand real workflows and guide improvements to key areas such as roof mapping, documentation flows and larger system-planning tools.

As the company’s primary designer, I took charge of product design direction across all software projects and worked closely with the MD on SAAS sites, the shop site, and wider brand development, ensuring a coherent and professional experience across the entire product ecosystem.
