This project is protected by a non-disclosure agreement, so I cannot show internal screens, visuals, or confidential product decisions. What I can describe is my UX process: turning low-fidelity requirements into complete, safe, and implementation-ready user flows for a complex in-car experience.

Plan
Start from feature requirements, map the complete user journey, identify missing states and corner cases, document every interaction in detail, and prepare the flow so developers could implement it without ambiguity.
From one screen to complete flows
For several features, I received low-fidelity requirements or an initial screen and expanded them into full interaction flows. I connected screens, reviewed every possible user path, and made sure the experience covered expected actions, edge cases, missing states, and potential errors.
- Created complete user flows from early feature requirements.
- Checked where users could click, what could happen next, and which states needed to exist.
- Reviewed flows carefully because safety and clarity are critical in a driving context.
Interaction documentation
Alongside the Sketch flows, I documented the behavior of interface elements in Excel. This included element states, triggers, origin and destination screens, behavior after interaction, status changes, and implementation details.
- Documented every relevant element, status, trigger, and transition.
- Reduced ambiguity for developers by describing what should happen in each scenario.
- Helped ensure that no blank spaces were left for implementation teams to interpret on their own.
Feature areas
My work included UX flows and documentation for feature areas such as weather, music, email, e-shop experiences, and China-market adaptations. Each area required careful attention to interaction logic, market requirements, and safe in-car usability.
Outcome
The work helped transform early requirements into detailed, developer-ready UX documentation. My focus was to make complex infotainment interactions clear, complete, and safe for users while giving development teams the clarity needed to implement the flows accurately.
