UX design, UX research for e-commerce and games, and UX management - the four ways I work, and the case studies behind them. Each area has its own home; this page brings them together.
Heuristic + targeted user testing on your live store. Prioritised fix list.
Moderated and unmoderated. Mobile, desktop, tablet - incl. real cart flows.
Cross-channel maps grounded in interviews and analytics. Not a slide-ware exercise.
Card sorts, tree tests, navigation rework - for catalogues that have outgrown themselves.
Qual + quant. Recruiting included.
Facilitate teams to align on what to test, ship, drop.
Moderated sessions on prototypes, vertical slices, builds. We test what's actually fun.
Genre work, motivation research, art-style reads. In-person Warsaw or remote.
Comp landscape, genre conventions, competitor teardowns. Fast and opinionated.
Where players churn, why, and what to change. With a fix list, not a deck.
Long-form qual with target segments. Recruitment included.
Quant studies with proper sample frames. No SurveyMonkey theatre.
Hire, coach, defend the team. Goals, 1:1s, careers.
Translate research into bets. Roadmaps that survive contact with reality.
Lightweight rituals, useful artefacts. Less ceremony, more shipping.
Recruitment, repository, repeatable methods. The unsexy plumbing.
Workshops, alignment, decisions made out loud.
Junior researchers, IC track, manager track. Office hours included.
End-to-end flows, from first wireframe to polished, build-ready UI.
Interactive prototypes in Figma and Axure. Code prototypes when they answer the question faster.
Pattern libraries, style guides and tokens that keep teams consistent as they scale.
Flows, navigation and information architecture that match how people actually think.
HTML, CSS and JS specs engineering can build, Tailwind included. No throwing it over the wall.
Workshops, design sprints and critique that move a team from arguing to deciding.
Every published case study, across all four areas. The label shows which area each one belongs to.
