The challenge
Perenna set out to change how mortgages work in the UK. Their product was new, but the experience still felt like old banking. The goal was to design a compliant, intuitive tool that made complex decisions feel clear and manageable.

My role
As Chief Design Officer at MOHARA, I led the strategic design of a mobile-first calculator that guided users through eligibility checks and personalised mortgage options, without unnecessary jargon or friction.
What we made
We mapped the full journey through stakeholder workshops and rebuilt the interface around simplicity. The backend handled complex financial calculations, while the frontend stayed focused and accessible.
The impact
The result was a tool that made a complicated process feel straightforward. It was built to support business needs, meet regulatory requirements, and reflect the modern product Perenna had created.
