Complex platforms. Clear daily work.

No process theatre. This is about judgment: what we build, what we leave out, and how I stay in the same rhythm as product and engineering.

1. 01

   Start with the problem

   I start with interviews, data, and the user’s day. Screens come once the team means the same problem — and knows how we will recognise success.

2. 02

   One direction, then iterate

   I don’t show ten variants just for the sake of variants. We set a direction that brings business, feasibility and use together — and sharpen it with real feedback.

3. 03

   Build with engineering

   I work in the same rhythm as product and engineering: prototypes, critique, specs. Design is part of the build, not a handoff at the end.

4. 04

   Keep going after launch

   What holds up in daily use is what counts. After launch I look at usage and friction — and keep sharpening, instead of closing the file.

5. 05

   AI for speed, judgment stays with me

   I use AI to summarise, to explore variants, and to draft specs. Research, trade-offs and the decision of what we do not build stay with me.

I am Christian Greven, a senior product designer based in Switzerland. I cut complex marketplaces and platforms so teams and users can hold them in daily work.

As employee no. 7 at DEINHANDY I built design from nothing: team, process, system, product. Later, at Tamedia and SMG Swiss Marketplace Group, the work centred on complex journeys — research, flows, launch.

I look for environments where design has a seat at the table. Permanent or mandate — as long as the problem is real and the collaboration is at eye level.
