Senior Product Designer focused on AI-driven B2B SaaS products that scale revenue and product adoption.
What I'm looking for
I am a Senior Product Designer with 8 years' experience building AI-driven B2B SaaS and SportTech products, delivering measurable business outcomes such as a $5.3M exit and scaling a product to 1,200 clients. I lead end-to-end product design, establish scalable design systems, and optimize core flows to improve conversion and time-to-market.
I specialize in AI prototyping and data-driven UX—accelerating MVP delivery, increasing scenario completion speed by 2.5x, and boosting trial-to-paid conversion by 58%. I mentor teams, align design with business metrics, and design automated AI experiences that drive partnerships and revenue growth.
