The only way to accurately manage your cortisol, weight, sleep and more.
Designing a long-term health system around biological reality
Pardigm is a next-generation health platform designed to help users understand and regulate cortisol, the body’s primary stress hormone, through continuous measurement and personalized action plans. The product combines at-home diagnostic testing with an AI-powered mobile application to translate complex biological data into clear, actionable guidance for long-term health improvement.
I worked closely with scientists, researchers, and the founding team to design a scalable, science-driven product system that supports users over months, not moments. The engagement focused on transforming advanced medical research into an accessible, trustworthy, and motivating experience, capable of supporting a wide range of health goals from stress and sleep to fertility, performance, and longevity.
A science-based platform for understanding and balancing stress
Pardigm redefines how people engage with their health by making cortisol measurable, understandable, and actionable on a daily basis. Using a simple saliva test scanned through a mobile app, users can monitor their cortisol rhythm in real time and receive personalized recommendations across five core areas: nutrition, exercise, sleep, wellness, and mindset.
The product goes beyond measurement. Based on cortisol curves, user goals, and medical context such as age and gender, Pardigm delivers structured, multi-month action plans supported by educational content, behavioral psychology principles, and access to specialists. The result is a holistic health platform that treats stress not as a symptom to suppress, but as a system to understand and regulate over time.
Turning biological data into sustainable behavior change
The primary goal was to create a scientifically credible yet accessible product capable of translating complex hormonal data into long-term, personalized health programs. This required designing a mobile experience that users could trust, understand, and follow consistently, even when dealing with abstract or unfamiliar medical concepts.
Key business objectives included educating a broad audience about the impact of cortisol on health, reaching users across diverse use cases such as weight management, sleep disorders, fertility, menopause, athletic performance, and mental health, and building a scalable platform capable of supporting hundreds of thousands of users globally. From the outset, the challenge was to balance medical rigor, personalization, and long-term engagement within a single, coherent product system.
Science-led discovery and system-oriented product design
Pardigm is fundamentally a science-driven product, which made discovery and research the most critical phase of the work. My process combined deep UX research, scientific collaboration, and strategic synthesis to ensure that every design decision was grounded in medical validity and real user needs. The work began with extensive research, including trend analysis, competitive analysis, cognitive journeys, user shadowing, stakeholder interviews, and direct collaboration with scientists and doctors. This allowed us to understand not only the science behind cortisol regulation, but also how users perceive stress, health data, and long-term behavior change.
Through synthesis workshops, personas, service blueprints, and value proposition design, we translated scientific insights into a clear product strategy and system architecture. I then led the design of the end-to-end experience, from scanning saliva tests and visualizing cortisol curves to structuring the recommendation engine and long-term action plans. The product evolved through four major iterations, with continuous feedback loops involving users, developers, researchers, and scientists. Close daily collaboration across disciplines ensured feasibility, accuracy, and coherence across design, technology, and science.
Building a foundation for scalable, personalized health
Although the product is currently paused, the work resulted in a fully designed, validated, and iteration-ready platform with strong early traction and market interest.

Designing for health as a long-term system
Balancing cortisol and improving health is not a short-term task. It requires sustained behavioral change supported by education, motivation, and professional guidance. For this reason, the product strategy focused on long-term engagement rather than quick wins.
The platform was designed to support multi-month programs, integrating access to specialists such as psychologists, tools inspired by behavioral psychology and CBT therapy, and gamification mechanisms to sustain motivation. My role extended beyond interface design to shaping the entire support system around the user, ensuring that data, recommendations, and human support worked together as one coherent experience.
From measurement to meaningful change
Pardigm addresses a fundamental gap in modern health care: the inability to measure and manage chronic, latent stress in everyday life. By combining at-home cortisol testing with a personalized digital platform, the product empowers users to understand how stress affects their body and how small, consistent actions can improve their health over time. The result is not just a mobile app, but a comprehensive health system designed to help users regain control over their biology, build healthier habits, and invest in long-term well-being.
