I'm a Lead UX Designer at HERE Technologies in Berlin. My work lives where regulation, dense data and human judgment collide: logistics, location, AI-native tooling, billing and compliance. The shorter version, I make the parts of B2B software most people would rather not look at, usable.

My background is industrial and service design before product. That mix is the thing I keep coming back to. I think in systems and in objects at the same time, which is useful when a problem spans an LLM, a billing pipeline, a customer success team and an invoice a CFO has to defend. I went from BSc Industrial Product Design in Istanbul, to an MSc in Product-Service System Design in Milan, into roles at IBM (NATO account), Bosch, Ticketmaster, Spark Networks, and now five years at HERE.

What I'm good at: framing the right problem before designing the solution, building hypotheses I can actually kill, and getting engineering, finance, product and CS to agree on the same artifact. Recent results I'm proud of: HERE Developer AI Assistant retention 3% to 18%, support tickets down 30%, credit memos down 96%, self-resolution 40% to 75%. None of those moved because of a visual; they moved because the team aligned on a smaller, sharper problem.

Outside work I'm pretty active. Pilates and weight training keep my head clear, and I travel as often as I can, mostly to learn how other cultures eat, dress, and decorate their rooms. I'm a committed foodie, an obsessive observer of interior and fashion design, and I spend more time in galleries than is strictly reasonable. Most of my taste in product work comes from that non-screen world.

The journey · 11 years

Eleven years of shipping software people actually use, now leading UX for AI-native B2B tools.

I'm happiest when the problem is tangled (regulated workflows, dense data, the human systems around them) and the job is to make something that feels obvious in hindsight. Click any role below to read the longer version.

The path here

  1. 2026 → now

    • Leading design for LLM-native B2B tools currently in build and test: route optimisation, logistics long haul, traffic analytics.
    • Drove HERE Idea Hub end to end as design + product lead: an internal accelerator where employees submit AI ideas, find collaborators and form teams, so a 4,000-person org stops re-running the same idea in five places. Set the vision, brought engineering, innovation and leadership stakeholders into alignment, and shipped it as a working product.
    • Mentoring designers on the team and aligning UX with product and engineering through cross-functional workshops.
    • Hired alongside the team for a Conversational Designer role to grow LLM design capability.
    • Contributed UX to a mobile delivery app, sharpening field-level operational flows.

  2. 2022 – 2025

    −96%Credit memos+15 ptsAI retention−45%Time to resolve
    • Usage Alerts: drove the strategy and design end-to-end. Credit memos down 96%, PayGo adoption at 30%, validated by enterprise customers.
    • When engineering ruled out direct cost display, I reframed the problem from cost transparency to anomaly detection , percentage-based comparisons that shipped as the solution.
    • HERE Developer AI Assistant (LLM-based): 4-week retention from ~3% to ~18% (+15 pts), self-resolution from 40% to 75%, time-to-resolve −45%.
    • Usage Management redesign: support tickets −30% through clearer cost visibility and self-serve controls.
    • Contributed components, NFI templates and error-state patterns into the HERE Design System.
    • Onboarded new designers with a structured journey through HERE ways of working.
