Building trust into a skeptical market: a biohacking social app. MOZA is a US startup building a biohacking social platform — a place to run supplement "self-experiments," share results on video, and vote on what actually works. Outcome Working solo on the design (with a design lead reviewing and joining client calls), I delivered the full mobile app and a complete UI kit built from scratch. I validated the design with 10–15 of the client's creators during the project. After handoff, I had no access to production analytics, so this case is honest about what I designed and tested, not about post-launch numbers I can't verify. Full product design, 0→1 Every flow, screen, and state: from onboarding through experiments, results, shop, and subscriptions. UI kit from scratch Colours, components, product patterns (self-experiment cards, subscription plans, the "My Answer" result visualisations), an illustration set that the team could build and scale on.
