Selected work
All projectsHow I work
I start with the business problem.
Stakeholder and user interviews come first, so complex requirements turn into flows people can follow.
Research decides, not taste.
Analytics, heatmaps and usability reviews show where journeys break and which fixes matter most.
I design in systems.
Components, variables and tokens keep products consistent across app, web and mobile web.
I ship with the team.
Prototypes, handoff and design reviews with PMs, developers and analysts until it's live.
What I do
