I turn complex systems into products that feel simple.

Senior Product Designer working on B2B platforms and operational tooling. I am usually brought in when the domain is complicated, the requirements conflict, and nobody agrees on what the thing actually is yet. Currently in ad tech, on rewards infrastructure.

Open to senior and lead roles Hamburg, working remotely 7+ years

Selected work

Four projects, chosen for the decisions rather than the screens.

Each one includes the reasoning, the tradeoffs I accepted, and what it changed for the business.

01Offerwall platform, internal operations

Getting the company out of its own support queue

Account managers were resolving every user level reward dispute by hand in a tool built for nobody. I designed the investigation model that let support answer for themselves.

02Offerwall platform, partner onboarding

Sixty settings nobody could explain

Publisher setup ran through one narrow dropdown of sixty plus configurations, labelled by the engineers who built them. Ninety percent had no documentation of any kind. I spent two months establishing what they actually did, then rebuilt the flow around that. Deal to release dropped from seven weeks to five.

03Promotions, lifecycle and operations

Arguing for the project nobody had funded

Promotions drove around ten percent of platform revenue and were managed through a table with two statuses and a search box. The design work was straightforward. Getting engineering time allocated to it, against far larger projects, was the actual problem.

04Design system, foundations to governance

Closing the gap between what shipped and what we drew

Two dashboards had drifted from the library and from each other. I audited both, rebuilt the foundations as tokens, refactored ten components with full state coverage, and structured the system so coding agents can read it. Weekly frontend review dropped from three to four hours to under one.

About

I am most useful before the interface is obvious: when the model is unfinished, ownership is split, and the team needs a decision it can build around.

My work moves between product framing, system design, and the operational detail required to ship. I stay close to engineering constraints, make tradeoffs explicit, and return after release to find out which assumptions survived contact with real use.

The path

  1. 2024 to nowadjoeRewarded ads platform, two dashboards and the design system
  2. 2022 to 2024InsiderMartech, led the Mobile Suite team
  3. 2021 to 2022GetirConsumer super app, launched car rental
  4. 2018 to 2021Koç UniversityBranding and interface work for startups and NGOs

Consumer speed first, then marketing tooling, then platform infrastructure. Each move took me closer to where a wrong decision has a measurable cost.

Worked with

What the people I worked with say.

Before Erdem joined my team, I had issues working with designers: messy Figma files, missed states, and a communication gap between teams. Erdem was a brilliant designer, and a friend, who did not just push designs to development but gathered everyone's input to mature the solution together. During handoff, every question we had was either resolved or got real attention from him. He turned our design to release cycle from a challenge into something to enjoy.

Erdem is that magnetic force that keeps cross functional teams with very different backgrounds engaged and together. He creates a space where laughter meets rigour. He has a unique approach: he executes meticulous design work and then delivers it with a good portion of dad jokes. As we worked together, he inspired me in my own leadership journey. It was a blast to work with him.
DÖDuygu ÖzgülDesign Lead, Insider
In a fast paced company with a lot of tech debt, Erdem always found a workaround. Sometimes an alternative design, sometimes more detail on how our product is structured. What he does best is provide solutions rather than become a bottleneck when times are hard. I really enjoy his approach as a proactive problem solver.
PPuruSenior Frontend Engineer, adjoe
Getir has a speed culture, and design has to respond to every requirement at once: C-level requests, legal pushes, fast growing market demands. Under all that pressure, Erdem was one of the solution makers in my team. I relied on him for multiple projects and crises, trusting him to take a brief from me and finalise it end to end.

If the problem is genuinely complicated, I am interested.

Open to senior and lead roles in B2B and platform teams. Happy to talk through any of the work above in detail.
