■ Senior UX Designer / 8 years / Munich, CET
I design products that turn complex rules into simple decisions.
I’m Elif, the first UX designer at Oscar, a car rental marketplace of local dealers in Europe and the US, and founding product designer of ArchiVinci AI, used by 800K+ people. My work spans booking and checkout flows, partner tools, design systems, experimentation and AI. Before product, I was an architect.

Munich
home base, working across Europe on CET
I design products that turn complex rules into simple decisions.
■ 01 Selected work
Three projects, end to end
Oscar · Customer booking website · 2022–now
B2C booking website for rentals and monthly subscriptions, tested market by market
I reworked search, checkout and insurance for customers booking cars from local dealers, added subscriptions as a second product, and validated changes with crowd tests and A/B tests.
ArchiVinci AI · AI product, 0→1 · 2024–now
AI rendering tool architects trust, from first launch to 800K+ users
As founding product designer I own discovery, product decisions and UX. The core problem was trust: giving architects control over AI output without adding a learning curve.
Oscar · Partner web and app · 2022–2024
B2B tools for booking and fleet management: a backoffice mobile app and a web-app for desktop
Planning happens at a desk; verification, keyless hand-overs and damage reports happen at the car. I designed both tools around that split, and the design system they share.

Systems, side projects and where it started
ArchiGPT · Chat-based AI · 2025
Chat-based rendering
For people who have never rendered: upload a photo or sketch and chat your way to a design, with suggestions and every decision explained. Designed end to end.
Oscar · Design system
One system, five surfaces
Booking web, customer app, partner back office, internal tools and fleet management, on one design system I built from scratch as Oscar’s first UX designer.
FASHION AI TOOL · 2024
Try-on web-app
UX/UI design for an AI-powered fashion tool, creating intuitive experiences for virtual try-ons, outfit generation, and personalized styling.
■ 03 HOW I work
Three habits behind the work
A
Start from the rules
Legal steps, pricing and operations are design material. I map them first, so the interface can make them feel simple.
B
Design both sides
Every booking has someone who fulfils it. I give partner tools the same care as the customer side, because one breaks the other.
C
Ship, measure, iterate
I frame changes as hypotheses, test them with users and data, and keep improving long after launch.
■ 04 Background
From architecture to product
I trained as an architect and spent my first years planning buildings and managing projects in Istanbul. Designing interactive exhibits for a science museum pulled me into UX, and I haven’t left since.
Architecture still shapes how I work: systems thinking, respect for constraints, and attention to how people move through a space, physical or digital.
