About

I’m a hands-on product design leader who helps startups and growing companies turn complex products into clear, cohesive customer experiences. I work closely with customers and internal teams to uncover gaps, strengthen product and design foundations, and build systems that support growth. My work experience spans product strategy, UX, product design, design systems, brand, and marketing for B2B and B2B2C SaaS. I enjoy the challenge of working through ambiguous spaces and turning insights into shipped solutions.

Lately, I’ve been exploring what’s next and how AI can strengthen my practice. I’ve been experimenting with connected workflows across Figma, MCP, Claude Code, and Cursor, while making space for creative side quests. If your team needs someone who can connect product strategy, UX, systems, and brand, let’s connect.
