The work

By relationship, not by brand.

Who engaged him, on what footing, and what he did. Large names here were usually an agency's clients, and each page says so. Every line is labelled by the evidence behind it, and no outcome or metric is claimed for any of it.

Embedded partnership

Tonic, a London employer-brand agency: he was employed there 2016–2020, and it has been a client since. The organisations below were Tonic's clients, worked on within that partnership.

Direct clients

Organisations that engaged him themselves, with no agency in between.

  • The ADHD Clinic for Women websiteTitled Full-Stack Developer & Technical Architect.
