My Responsibilities
02 Health Care - B2C Market
One of the primary design and business goals is to find effective ways to translate and leverage accurate health data into meaningful insights that matter to users, helping them create a healthier lifestyle.
01 Conceptual Design to Execution
Redesigned and executed based off Pininfarina’s conceptual design to meet rescope, new requirements, feasibility constraint, and tight deadlines, delivering successful Phase 1 & 2 launches.
04 Mobile + Smart Watch Experience
Identifying the different needs and pain points of users across various platforms is a key step in creating a seamless mobile app and smartwatch ecosystem and user experience.
05 Design Process Integrated into Weekly Sprints
Initially, this project operated under agile management with weekly sprints, leaving little time for design process and usability testing. Together with the Human Factors team, we outlined our design process and communicated its impact to software engineering and upper management, successfully integrating it into the weekly sprints.

Project Timeline
Transition To In House Design
In 2021, Masimo collaborated with Pininfarina design agency to envision and develop the concept and branding for the Masimo Health app and Freedom smartwatch.
During 2023, I joined the project when the design was brought back in-house. Our goal was to transform the conceptual design from Pininfarina into execution while incorporating new scopes and directions to enhance the overall user experience, visual, and functionality.

03 Google Partnership
We have integrated Wear OS into the Freedom smartwatch and received approval from the Google Design team, which facilitated our partnership with Google in 2024.
Week 1 - Feature Prioritization and Scope
Together with the PM, Marketing, and User Research teams, we spent 2 days prioritizing activity features using the MoSCoW method. The decisions were based on user needs, user and competitor research, business goals, technical constraints, and project timeline.
Week 1-2 - Identify Watch + App User Flows
The design team will develop the use cases and user flows, with the PM joining later to review and ensure all use cases are captured, the flows are feasible and logical, and technical edge cases are addressed.
Week 2 - Cover All Use Cases
While we are developing the user flows, the PM will start drafting user stories based on the flows we have created. We will iterate on the flows and user stories, ensuring they align with user needs, business goals, while addressing technical constraints and ensuring feasibility with developers and algorithm.
Week 2-3 - Create Wireframes
The design team will develop wireframes for the app and watch based on collectively agreed user stories. Once approved by stakeholders, PM, algorithms, and developers, we will proceed to high-fidelity UI design.
Week 3-5 - UI Design Iterations
2 weeks for UI exploration including design review with higher up and all departments.
Week 6 - User Testings
Once the design is approved, the design team will provide prototypes for the user research team for user testings to validate the concepts, usability, and accessibility.
Week 7 - Handoff
After reviewing user test results, the user research team will discuss feedback with us and we will then update the design accordingly. A follow-up review will be conducted before handing off the final design to developers.
