UXellence is my independent UX practice. I take on research, interaction design, design systems and accessibility work directly: one senior practitioner rather than a pyramid, with scope and duration fixed wherever the problem allows. I also publish the toolkits and assessments that came out of that work, including EN 301 549 conformance templates and a fixed-scope European Accessibility Act exposure report.
