During the summer of 2025, I interned at Cathay United Bank. In just two months, I worked on three projects, quickly gaining an understanding of the bank’s internal design systems and guidelines. I independently designed wireframes for a low-code tool and developed data visualization chart specifications based on D3.js.
SCS Security Control System Enhancement
Phase III of the Security System Restructuring Project
Goal
Improving the internal employee data management system
Role / Responsibilities
❇️ Understanding BU Needs
- Interviewed users to identify current usage issues
- Clarified terminology definitions and operational logic
- Considered exceptional usage scenarios
- Used empathy to uncover key pain points and real needs
❇️ Collaboration with System Analysts (SA)
- Identified and consolidated screens with similar attributes
- Removed outdated or deprecated functions
- Verified technical feasibility
- Understood backend development logic and API call timing
❇️ Design Review
- Discussed which component modules to adopt
- Reconfirmed workflow details
- Explored alternative design approaches to reduce development costs while achieving the same goals
Internal Low-Code Tool
Designing an internal system interface development tool
Goal
A wireframing tool to reduce internal communication costs
Role / Responsibilities
❇️ User Research (Employees)
- Previously, BUs communicated requirements to designers using Excel and PowerPoint
- This method made precise communication difficult
❇️ Competitive Analysis
- Summarized common design features
- Presented essential functions and exemplary design references
❇️ Workshops
- Brainstormed interface operation requirements and basic functionalities within the team
- Considered development constraints and expectations of different stakeholders
❇️ Information Architecture & Interface Wireframes
- Through multiple proposals and iterations, finalized the main workflows, key functions, and button placements
Chart Component Specification Writing
Developed design specifications for D3.js pie charts and other types of data visualizations
Goal
Developed design specifications for various data visualizations
Role / Responsibilities
❇️ Chart Design Meetings
- Held sync meetings with frontend developers and designers
- Learned how to properly document specification files
❇️ D3.js Parameter Testing & Configuration
- Reviewed official documentation of open-source libraries
- Tested different parameters to evaluate visual effects
❇️ Interaction Specification Writing
- Considered diverse usage scenarios and design features
