§ 001 · About
Mahdi Fazel, Senior Product Designer
Mahdi FazelMF / 26

I design the quiet systems that carry complex products.

Nine years and four thousand organizations in, my work sits where business outcomes meet craft. I partner with fintech, SaaS, and complex B2B teams to turn blurry problems into interfaces their customers trust and their operators can defend.

I come for the hard parts: multi-role dashboards, permissions, compliance primitives, workflows that stretch across teams. I leave behind a system. Tokens, patterns, documentation, and a product that keeps its shape when the next designer arrives.

Let's build something measurable.

I'm open to a senior product design role this quarter. Fintech, SaaS, or complex B2B teams where systems thinking is the point.

§ 006 · Questions

Before we start talking.

A short list of what I'm usually asked before a first call. If you have something specific, email works.

  • A senior or staff product design role I can grow with: full-time, permanent, hybrid in Berlin or remote-friendly across the EU. I work best when I'm accountable to a business outcome over many quarters, not a single launch.

§ 007 · Notes

A short note every few months.

Process notes, pattern breakdowns, and whatever I'm reshipping. Low frequency, no funnels, no pixels.
