A selection of projects spanning accessibility leadership, UX transformation, usability improvements, conversion optimisation, design system development, and large-scale digital transformation.

Inclusive Digital Transformation

Designing Better Experiences
I enhanced the usability and conversion of Macmillanâs key fundraising journeys through research-led UX improvements, redesigning complex flows to create clearer and more effective digital experiences.

Learn more about meWhat People Say
Iâm grateful to have worked with talented teams, leaders and partners across several organisations. Hereâs what some of them have said about collaborating with me.
"Just a small note to say a big thank you for everything youâve done for me over the last two years. I really appreciate you welcoming me into the team, being an amazing manager (and friend!), and for keeping us all sane during such a crazy time in the world!Â
Thank you also for the opportunity of having Life Coaching sessions with you. Your coaching was a huge help in building my confidence, discovering my goals and working towards them. With your support I was able to achieve what I really wanted: working independently and have flexible working arrangements.
I will really miss working with you but I hope we will be able to work together again in the future."
Olivia G., UX Designer
"I have been having coaching sessions with Aga over the last few months. She has been coaching me on UX/UI Design and how to move into this area. [...] She has also sent me reading materials, talked through key UX terms, and pointed me in the direction of where I can get training etc. This has been great as I was finding it all a bit overwhelming and wasnât sure where I should start. Aga helped to break it down into smaller âchunksâ so it was easier for me to manage and work through.
Our sessions are not always all about UX/UI design, as we cover other areas of life and Aga has provided guidance on how to manage stress and helped talk through the best ways to manage my time. [...] Aga is an expert and is very knowledgeable in her area and I would recommend her to other people."
