Behind the design

Challenges I faced — and how I solved them.

Designing one product for iOS, Android and web meant constant trade-offs between consistency and platform-native feel. These were the hardest problems, and the decisions I made to resolve them.

01 · Trust Earning trust on a high-value transaction Renting a car is a big, anxious commitment. Early testers hesitated at checkout, worried about hidden fees and the car's real condition.

How I solved it An all-in price breakdown shown before checkout, "no hidden fees" reinforced throughout, verified reviews tied to specific cars, and a clear free-cancellation promise on every screen.

02 · Complexity A booking flow with too many variables Location, dates, car class, insurance and extras created a long, intimidating form that caused drop-off in the first prototype.

How I solved it I split it into a guided sequence — search → fleet → car detail → dates → checkout — with a persistent booking summary, so users only make one decision at a time and always see the running total.

03 · Multi-platform One brand across iOS, Android & web The bold Anton/yellow identity that felt great on a dark web hero risked looking heavy and cramped in a dense mobile list view.

How I solved it I built a shared token system — same colors, type ramp and components — but let density adapt: airy dark marketing pages on web, lighter high-contrast cards with bigger tap targets on mobile.

04 · Confidence Choosing the right car, fast With a mixed fleet, users couldn't quickly tell which car suited their trip — leading to back-and-forth and abandoned sessions.

How I solved it Category filters (Economy/Sedan/SUV/Luxury), at-a-glance spec chips and honest photography on every card, plus a detail page with an explicit "what's included" list to remove guesswork.

What I'd do next Run moderated usability tests on the checkout, add a map-based pick-up picker, and prototype the in-trip experience (unlock, extend, support) to close the loop after booking.
