Defining 30+ Screens for a Six-Engineer Team
The company shipped it. It later passed 10,000 users, after my engagement ended.
Problem
EV charging is a multi-step service. It had to become one clear mobile flow that engineering could build from.
The screens had to follow the real steps:
- Find a charger.
- Check availability.
- Start a session.
- Manage payment and session state.
- Handle edge cases clearly.
What I did
- Reviewed competitor EV charging apps to inform scope.
- Turned the charging service into a structured mobile flow.
- Designed the full screen structure: 30+ screens across the charging experience.
- Worked with the six-engineer team to keep the backlog clear and the build direction defined.
The flow
Where it ended up
The company shipped the product.
It later reached 10,000+ users, within months of launch and after my engagement ended. I count that as product context, not as a growth result of mine.
