Why work with me

✦ Summarised by AI from my feedback and recommendations
  1. 01

    I get things done (and done well!)

    I don’t just design pretty screens—I make sure my work is clear, actionable, and actually helps the team move forward. No fluff, just impact!

  2. 02

    Great teammate, zero ego

    I love bouncing ideas around, taking feedback, and working closely with PMs, engineers, and other designers. Collaboration makes everything better!

  3. 03

    Problem-solving is my jam

    Give me a messy, complex challenge, and I’ll break it down, find the best solution, and make sure it works for everyone—users, stakeholders, and devs alike.

Kind words

“Sarah is a fantastic designer and all round excellent colleague… If you are lucky enough to get the chance, you should hire her at once!”

About me

My professional approach encompasses attention to detail, complemented by a deep understanding of business requirements, allowing me to craft innovative solutions. Simplifying intricate problems, through discovery to develop design solutions that cater to the diverse needs of project stakeholders and users.

Going beyond my role, I actively collaborate with PMs by showcasing strong commercial acumen and proposing practical solutions. In close partnership with engineering, I navigate technical constraints while advocating for an enhanced user experience.

These days I’m a new mum, building Niblet in the moments in between. Weekends are for hikes with my husband and Vera, pub lunches and cake.
