Flexcar is the first — and only — month-to-month car lease, designed for people who want freedom without long-term commitments. Users can subscribe to a brand-new car, from a Toyota Corolla to a Mercedes-Benz, with everything included: insurance, maintenance, 24/7 roadside assistance, and no hidden fees. It's car ownership reimagined — zero down payment, zero debt, and fully managed through a seamless digital experience.
Growing the number of active subscribers
Increasing user retention
Reducing fleet maintenance and repair costs
Speeding up the time-to-market for new vehicles
As a Senior Product Designer, I’ve been leading core UX and UI initiatives across iOS, Android, and web — collaborating closely with product managers, engineers, and stakeholders to solve both user and business needs. I also own and maintain the mobile design system, ensuring consistency and scalability across platforms.
In addition, I mentor teammates on UX patterns, especially around fleet management tools — drawing from 4+ years of experience in smart mobility and carsharing.
Alongside core product work, I also streamlined how we build and ship promo and marketing pages. I introduced Framer as our main tool and built a fully autonomous workflow — from design to implementation — which cut time-to-market by 50% and saved the company tens of thousands of dollars in dev resources.
But today, I’d love to share one of my favorite product cases: Safe Driving Program (Driving Score)
Safe Driving Program
Driving Score was the first major feature I took on after joining Flexcar. Earlier, I had designed a similar feature for Belkacar, and saw an opportunity to adapt those learnings while rethinking the experience for a different market, user base, and product model.
My goal: design and ship a new experience inside the mobile app that would:
Visualize a user’s driving score
Explain how the score is calculated
Fit seamlessly into the broader product experience
Motivate safer driving behavior through design
The long-term business goal was to reduce accident rates and vehicle wear-and-tear.
In the first 3 weeks, I worked closely with product and engineering — digging into the data model, understanding telematics constraints, and gathering market references.
In parallel, I explored dozens of design directions — testing how to visualize the score, structure insights, and deliver motivating feedback.
The real challenge wasn’t just showing the score — it was designing around:
Uneven zone distributions on the score bar (nonlinear logic)
Business mechanics around rewards, penalties, and thresholds
Dozens of iterations, concepts, and directions explored before narrowing in.
I documented how the arc works — including z-index layering and behavior.
Some of those early explorations and how they evolved into the first production version.
Final experience
Rewarding safer driving. Visibly.
At-a-glance feedback on the home screen
Right from the home screen, users can see their current driving score and how close they are to earning their next reward. The score card dynamically adapts based on performance — the progress bar color, background, and supporting text shift depending on their zone. It also shows how many days are left until the monthly check-in and what the user can earn. An info button opens a bottom sheet with a clear explanation of how the score system works.
Breaking down the score
To help users understand what affects their score, I added a detailed breakdown into seven subscores. They're grouped into two sections: “Where you shine” and “Where to improve.”
Each subscore opens a short modal with a plain-language explanation and simple tips for how to get better. The goal was to turn black-box scoring into something clear and actionable — not just for power users, but for anyone using the app regularly.
Understanding progress over time
I designed the history tab so users can track how their score has changed month by month — what rewards they earned, when they missed, and what zone they landed in each time.
It’s a simple timeline, but it gives structure to the experience. Instead of feeling like random scores, users start to recognize patterns in their driving habits and outcomes.
First-time introduction
To support the rollout, I created a short onboarding flow that introduces the Driving Score feature step by step. It’s modular and designed to be reused in future features.
The flow highlights the core mechanics — how the score works, how to earn rewards, and what to pay attention to. The goal was to explain just enough without overwhelming, and make sure users knew exactly what they were getting into.
We delivered the MVP in about a month. It wasn’t simple — there were tricky edge cases with billing, data inconsistencies from the telematics API, and a lot of back and forth with engineering.
But we shipped. We launched to a limited cohort, iterated fast, and worked closely with analytics to monitor early signals, user behavior, and model calibration.
V2 Update
Four months in, we shipped a major update shaped by real-world usage and user feedback:
Outcome
–15–18% accident rate reduction — since launch. Long-term, this means lower repair costs and longer vehicle life
Increased user engagement and loyalty — people actively tracked their score, came back near check-in days, and strived to reach Reward status
Insurance benefits unlocked — by tracking score and driving patterns transparently, we created a foundation for offering insurance discounts to high scorers
I’m proud of how this feature turned complex data and business logic into something intuitive, motivating, and ultimately impactful for both users and the business.
And more
There’s much more I’ve worked on at Flexcar:
Mileage-based plan recommendations
Redesign of mileage tracking experience
Integrated support chat
Customer referral program
