Senior Product Designer · UI & Systems Specialist
Katharine Agg
Hi, I’m Katharine, a product designer with a focus on UI clarity and user empathy.
- 10+ years across sports tech, education, and social good.
- I align user goals with business strategy to design usable, scalable products.

A Short Story
I’m a Senior Product Designer specialising in UI, with a background in building scalable digital products that are as visually polished as they are strategically sound. My design process is rooted in empathy, collaboration, and a strong belief that beautiful interfaces should also solve real business problems.
Over the years, I’ve worked across multi-disciplinary teams to design web applications and design systems that improve usability, drive consistency, and help businesses meet their goals.
I also mentor junior team members and provide peer support for colleagues of any experience. At my last role I led Creative Club – a monthly initiative I founded to bring designers together for creative growth, shared learning, and open conversation.
What I Do Best
- UI design with a focus on consistency, clarity, and accessibility
- Strategic product thinking aligned with user and business needs
- Leading cross-functional design initiatives
- Building scalable design systems
- Mentoring and community building
My Approach
Design is a strategic tool – not just a visual layer. I approach every project by balancing user needs with business KPIs. My process often includes aligning early with product and engineering stakeholders, auditing the current experience, and using tools to analyse actual user behaviour. This helps ensure that design decisions are grounded in evidence and impact.
Whether I’m crafting a new product or optimising an existing flow, I always aim to make the experience seamless, efficient, and delightful.

With a background in physics, I bring a strong foundation in analytical thinking, problem-solving, and data-driven decision-making to my UX/UI design practice. My training taught me to approach complex systems with precision and creativity, skills I now apply to understanding user behaviour, designing intuitive interfaces, and testing hypotheses through iterative design. This scientific mindset complements my visual and user-centred approach, allowing me to create thoughtful, effective, and evidence-based design solutions.
