Some of the lovely reviews I've received from my clients and colleagues.


Jessica focuses on the proper level of detail and abstraction in her work and puts the user experience front and centre, encouraging other stakeholders to do the same.

Head of Product, Priceloop AI


We had a huge UX Design project in which we wanted to pull in a specialist to really help us take the project to the next level. Jess was extremely knowledgeable and professional. She constantly brought forward creative ideas to really help us elevate the project and was the lynchpin between the design team and tech team. The client was extremely impressed with her professionalism and level of detail. If you want a freelancer you can trust to work alone and do an outstanding job, Jess is the one!

Jessica's work creates order. Her intelligence and experience in the digital design process saves so much time. Her decade of digital problem-solving will guide you through whatever technical challenges you face. Her work brings in value on so many levels. She has created work for me that has helped me win several awards.

Jess does not implement designs, but looks for creative solutions! It's important for her to understand the background, and this quality is clearly noticeable in her work. With her experience, she is a super asset that moves any team forward.
