Short version

A designer who reads analytics and pushes back on PMs.

I lead product design end-to-end: research, prototyping, design systems, dark mode, Local Variables in Figma. Worked with B2B platforms, mobile startups and education products across Moscow, Tashkent and Brest.

Testimonials

What collaborators say

  • Sophie ran five dealer interviews and rewrote our product brief in a week. Three months after release we stopped measuring conversion in tenths of a percent.

    Product Lead

    B2B SaaS

  • A rare designer who reads analytics before designing, not after. The design system landed on Flutter without surprises — handoff took a week instead of the usual three.

    Founder

    Mobile Startup

  • Calm, argument-driven, not afraid to push back on PMs when she has the data. That is rare.

    Engineering Lead

    Education Platform
