About
I’m Sofia Fotaki, a Product Designer based in London with 12 years of design experience, including 5+ years building digital products across B2B SaaS and B2C platforms on desktop, iOS, and Android. I specialize in interaction design, information architecture, design systems, and accessibility, and I enjoy using AI-assisted workflows from discovery through delivery.
Recently, I led the 0→1 design of the Marriage Menu experience for a leading Muslim marriage app, partnering closely with Product, Engineering, and Growth to drive measurable outcomes—like a +12% increase in Menu revenue within two weeks of rollout. I also redesigned onboarding to improve conversions and retention, run A/B tests to guide decisions, and strengthen cross-functional collaboration by introducing more structured research, ticketing, and handoff practices.
