What I'm looking for

I seek remote roles where I can lead product and UX strategy, design AI-driven experiences, collaborate cross-functionally, and drive measurable user and business outcomes.

I am a Product Designer with 12+ years crafting user-centered digital products across AI, healthcare, travel, sports, gambling and hospitality. I specialize in conversational UX, AI interface design, and taking products from early-stage MVPs to full platform overhauls.

I collaborate remotely with distributed teams—founders, PMs, developers, and other designers—to ship products that work and delight users. I have led design efforts for large-scale apps and AI platforms, delivering measurable outcomes like doubled trial conversions and large increases in session duration.

My process blends user research, prototyping, and design systems to simplify complex workflows and improve retention and engagement. I enjoy defining product strategy, managing cross-functional teams, and building polished, production-ready experiences.
