Senior Product UX/UI Designer
Janine Prange.
I don't hand off designs. I build shared direction: products that teams believe in and users actually want.
15+ years of end-to-end product design. 7+ years in B2B SaaS. I lead without authority, set quality standards others follow, and deliver outcomes, not just deliverables.

How I work
Collaboration drives outcomes.
The best solutions emerge from building shared direction with product, engineering, and data. Not from advocating for a design answer and hoping the room agrees.
Research protects the team's time.
A validated direction costs almost nothing upfront. The wrong direction, discovered after shipping, costs everything. That arithmetic never changes.
Outcomes belong to the whole team.
When design, engineering, and product own the result together, the result is better. And so is the work that produced it.
