Why me?

My key strengths.

20+ years experience

My career has been defined by a deep understanding of user needs balanced with strategic business objectives to create functional, engaging, and visually coherent digital experiences.

Proficient in UX and UI design

With over twenty years of experience in UX and UI design I have built a strong foundation in product design, applying my approach consistently from concept through to final delivery.

Skilled in HTML & CSS

From an old world of hand-coding HTML and CSS I have a strong understanding of coding best practises and accessibility in the digital world that informs my product design approach.

Collaboration

I have cultivated the ability to act as a strategic bridge between technical requirements, business objectives and user needs. Translating these unique needs into a unified visual language.

Experience.
