Developed a documentation feature for the NHSDigital/prevention-services-design-history repository, capturing the methodology and outcomes of pop-up user research conducted at public libraries to enhance participant diversity in NHS vaccine studies. The work focused on creating clear, reproducible records using Markdown, with an emphasis on supporting public health research and future onboarding. Collaborated closely with stakeholders to ensure the documentation met governance and traceability requirements, consolidating changes into a single, reviewable commit. Leveraged skills in user research and technical writing to produce a reusable reference that strengthens research transparency and supports ongoing efforts to improve inclusivity in healthcare study recruitment.
