What I'm looking for

I’m looking to lead design engineering for product teams—owning end-to-end experiences, scalable design systems, and growth-focused UX with close engineering collaboration, where I can keep shipping polished interfaces and using AI to iterate faster.

I’m a Design Engineer with 5+ years of experience building cross-platform user-centered digital products. I evolved from Product Designer and Frontend Engineer, bridging design and code to create design systems, polished interfaces, and scalable experiences—while leveraging AI to accelerate workflows and iteration.

At Retrographic, I led design and development of core product experiences for Sprocket, delivering the Sprocket Design System and a full UI overhaul across desktop, tablet, mobile, and watchOS. I designed and optimized critical user flows (navigation, onboarding, marketplace, subscriptions, social sharing), driving 123% YoY ARR growth, 30–40% ASO conversion rates, and 345k app installs over 3 years.

As Cofounder/Design Engineering Lead at BuySub, I spearheaded the transition from manual operations to a robust automated marketplace and portal system within three months, single-handedly owning product design, branding, full-stack and database infrastructure. I’ve also freelanced as a Design Engineer/agency collaborator—shaping design systems, technical standards, and production-ready UI/UX—while scaling toward measurable revenue and strong client outcomes.
