At Portl Technologies, I own product design across UltraGym, UltraGym Pro, Studio Mirror, and companion experiences for connected fitness products.

I led UltraGym Pro end to end, from product discovery and interaction design through high-fidelity prototypes, developer handoff, and implementation across hardware and software. I also designed and launched Buddy Mode and Generate Workout, translating multi-user and personalized workout constraints into intuitive experiences.

I evolved UltraGym and Studio Mirror by identifying usability issues and prioritizing improvements with leadership, contributing to app NPS increasing from 2.5 to 4.5. I simplified the Functional Movement Screening flow from 12 movement exercises into a guided three-step experience through iterative testing with fitness experts and stakeholders.

My architecture foundation shapes how I approach product design: asking better questions, validating assumptions through research, and balancing usability, technical feasibility, and business goals. I collaborate closely with users, engineers, leadership, and business stakeholders to create thoughtful, user-centered experiences.
