What I'm looking for

I'm seeking senior product design roles focused on scalable design systems, UX+AI experiences, and cross-functional leadership in collaborative, growth-oriented teams; open to relocating to Singapore.

I am a Senior Product Designer with 10+ years leading end-to-end product design for global platforms, focused on delivering elegant, accessible UI/UX that aligns with business goals and user needs.

I translate complex requirements into scalable design systems and data-driven experiences, driving measurable results such as a 54% increase in MAU, a 56% improvement in discoverability, and notable gains in UI consistency and engagement.

My process combines qualitative and quantitative research, journey mapping, prototyping, and close stakeholder collaboration across APAC to ensure cohesive product outcomes. I have led teams, mentored designers, and managed design roadmaps to support enterprise, healthcare, and consumer-facing products.

I am passionate about the intersection of UX and AI and seek opportunities where I can lead system-level design, improve human-AI interactions, and contribute to high-quality, user-centered products.
