project overview
I built an MVP web portal that translates complex cancer data into actionable insights for healthcare providers and researchers.
Problem
From Cancer Research into Clinical Practice
Personalized cancer treatment remains difficult to deliver at scale. While advances like single-cell RNA sequencing offer unprecedented precision, adoption in clinical settings is limited by complexity, cost, and low clinician familiarity.
Goal
Transforming Complex Data to Actionable Cancer Insights
WittGen Biotechnologies aims to provide a web portal where clinicians and researchers can easily request and receive clinical reports based on single-cell RNA sequencing data.
Business Goal
To have as many users onboard the product and see high
Customer loyalty
Customer satisfaction
Customer retention
User Goal
To find a reliable source to use as a reference for cancer research and treatment
Project Goal
To launch an MVP demo successfully, showcasing the main features of applying for and receiving a clinical report
Research
Designing for Expert Users
I conducted literature reviews and collaborated with an internal researcher to clarify that the target users were scRNA-sequencing experts, which informed an experience focused on advanced functionality, streamlined workflows, and in-depth reporting.
hypothesis
Proposed Approach: Instant, User-Friendly Updates
Based on our research findings, we hypothesize that users need instant access to important updates, delivered through a fast, intuitive, and easy-to-use experience.
Competitive Analysis
Identifying Our Edge in the Market
One key consideration was identifying existing major players in the field. After analyzing WittGen’s competitors, we found no direct competitors addressing the same methodology or problem we aim to solve. This gap highlighted a clear opportunity for us to deliver a unique solution.
User flow
Bringing scRNA-seq into Clinical Workflows
Using scRNA-seq would be a new experience for most users, so this product especially carried the risk of the user falling into cognitive overload. It thus became our objective to first create a fast and intuitive user flow.
User submits data
AI-powered analysis
User receives clinical report
Rapid Prototyping and Iteration
Fast Iteration, Focused Feedback
After completing the user flow, I led rapid prototyping and iteration due to tight timelines. I created high-fidelity prototypes, continuously iterated on them, and collaborated closely with UX/UI, development teams, and stakeholders.
01 Simplifying Files
1
Weak distinction between My Files and Applications
2
Most applicants won't have rows and rows of applications
3
View only mode is unnecessary
02 Improving data upload efficiency
1
Users have to restart the whole application process if they have 2 or more file formats to upload
03 verifying before payment
1
Users must go back each step if they want to check their data input
The Final Product
MVP WittGen Portal
01 Dashboard
Upon portal login, the user is led to the dashboard, where an overview glance of recent file updates is shown.

Moving Forward as a UX/UI Designer
My first industry project had been a transformative experience for me. There was lots to be curious about, and thankfully with such amazing and encouraging designers to guide me, I feel I have grown exponentially as a UX/UI designer. With that said, here are some of my reflections:
Reflecting on Research and Process
In hindsight, deeper user research with interviews and user testing could have uncovered more valuable insights. With more time, following a traditional design process with detailed wireframes might have led to more refined and creative solutions.
Rethinking the Data Input Experience
The Excel upload feature aimed to simplify input but wasn’t inclusive for all users. In future iterations, integrating a vision API to extract text from photos could offer a more flexible and user-friendly approach.

02 Matching columns
Once the user uploads their excel file, they undergo a process of ensuring that their excel file's header matches the system's header.
03 Validating data
In case of errors in the file or during the import process, the user can edit their data to ensure all fields are complete and valid.
04 Review before payment
Reviewing helps prevent errors and reduces the need to contact support.

Research
Understanding Users: Medical Professionals with Specialized Expertise
I conducted literature reviews and held sessions with WittGen researchers, which revealed that our users are experts in scRNA-sequencing. Based on this, I designed the experience to include advanced features, efficient workflows, and detailed reports without basic explanations.
