Sid Ahmed Larbi Youcef

I’m a Lead UX/Product Designer with 6+ years of experience shipping end-to-end digital products across B2B SaaS, e-commerce, and growth platforms. I’m currently leading product design at Expandi for a platform used by 15,000+ users.

I drive measurable outcomes by owning product experience end-to-end—planning and running user research, translating insights into roadmaps, and partnering with PMs, engineers, and data teams to ship features that improve activation, retention, and expansion. I’ve led design across core product surfaces like campaign management, inbox & reply management, reporting dashboards, and a signal center.

I also build the foundations that help teams move faster: I defined and evolved a company-wide atomic design system (reusable components, design tokens, and interaction patterns) and championed AI-assisted flows and smart defaults to reduce setup time—helping even non-expert users succeed.
