What I'm looking for

I'm looking to lead end-to-end product design for web and mobile products, building scalable design systems and user-centered experiences with collaborative cross-functional teams.

I've led end-to-end product design for Usarion, weDevs' Dokan Cloud, Crowdbotics, and Feed U Technologies—turning complex web and mobile requirements into intuitive, developer-ready experiences. At Usarion, I built scalable variable-based design systems, including 50+ reusable components, and reduced developer hand-off time by 20%.

I've improved Dokan Cloud's mobile checkout, lifting renewals by 23.9%, and helped drive 3,700+ marketplace registrations through conversion-focused website UX. I enjoy shaping product strategy through research, workshops, user flows, prototyping, responsive design, and close collaboration with clients, stakeholders, developers, and design teams.
