Hi, I’m
Kazuki Ueda
Product
Designer

[Product Designer]

Product Designer with 5+ years of experience in healthcare SaaS, currently based in Osaka. I recently shipped Pintio — an iOS restaurant discovery app I built solo from concept to App Store. I handle everything from product strategy and UX/UI to React Native implementation through AI pair programming. At my day job, I design medical device apps and web platforms. On the side, I take on freelance projects for startups and brands.

At Work

At Heart Organization, I’m the Product Designer for a medical device app (iOS) and web platform used by healthcare professionals. I work across the full design process — from wireframes to production UI — always with implementation and long-term operation in mind. I also produce key visuals, thumbnails, and on-screen assets for live medical streaming events. In 4 years, I’ve created over 800 pieces — each designed to communicate complex medical information clearly, with strong attention to structure and information hierarchy.

Strong point

[Based on the Big Five]

I analyzed my past experiences and achievements through the lens of the scientifically recognized Big Five personality traits to gain a deeper understanding of myself.

Extraversion

Dynamic Balance

0%
My balance of extroversion and introversion has become a key strength in my role as a UI/UX designer. In the Caseline project, I was able to actively listen to feedback from doctors while also taking the time to reflect deeply and develop optimal solutions. When designing the administrator dashboard, a combination of engaging with various stakeholders and doing focused, analytical work was essential. My ability to switch between these modes allowed for effective project progression and successful outcomes.

Conscientiousness

Precise Execution

0%
Conscientiousness drives my meticulous attention to detail and commitment to delivering high-quality designs. In the administrator dashboard redesign for Caseline, I carefully analyzed user flows and ensured that every element aligned with both functionality and user needs. This focus on precision and responsibility resulted in a solution that improved operational efficiency.

Openness

Innovating with Openness

0%
My openness to new ideas and perspectives allows me to innovate and adapt in diverse projects. During the redesign of Caseline’s landscape mode, I explored multiple design approaches and integrated feedback from both engineers and medical professionals. This flexibility enabled me to create intuitive designs that aligned with real-world healthcare workflows.
