Aussie Exchange is a Java-Swing web application that pairs older adults in Japan with friendly Australian visitors for casual conversation, cultural sharing, or guided experiences. The goal: ease loneliness in Japan’s aging population while giving tourists a richer, people-first way to explore the country.

My Roles
Java-Swing Developer
- Implemented language-switching, authentication, and accessibility tweaks
- Refactored UI components after each round of user testing
Project Manager
- Set weekly milestones and kept the team of four on schedule
- Facilitated stand-ups & retros to maintain a healthy team dynamic
Documentation Lead
- Authored the localization summary, usability-test reports & final slide deck
- Ensured all deliverables met course and ISLO standards
The Problem
-
Social Isolation: Japan has the world’s fastest-aging population; single-person households and reported loneliness are rising.
-
Tourism Opportunity: Australian travel to Japan has grown 5× since 2010. We saw potential to connect these two trends for mutual benefit.
The Solution
-
Profile Browsing – Japanese users scroll a card-style list of vetted Aussies.
-
Secure Matching – Requests are encrypted; both sides approve before any contact.
-
Language Support – One-click language swap (日本語 / English); all labels auto-localize.
-
Accessibility First – High-contrast palette, scalable fonts, keyboard-navigable layout.
Cultural Localization Approach
We wanted to build more than just a translated app, our goal was to make Aussie Exchange feel natural and intuitive for Japanese users.
Research-First Process
Started with academic and online research to understand social issues in Japan (like loneliness among older adults) and cultural norms around design, privacy, and interaction.
Interviews with Cultural Experts
We talked with Japanese users and cultural experts to ensure our concepts addressed a real need, not just what sounded good to us.
Usability Testing:
Round 1
Our first prototype (Figma) focused on basic flow and structure. Feedback helped us fix spacing, labeling, and other quality-of-life issues.
Results
Usability Testing:
Round 2
The second prototype was built in Java Swing with full functionality. We tested it with four Japanese users (either native or fluent). Their insights changed everything.
JP Font Matters
Default Java fonts appeared Chinese. We switched to MS Mincho, a Japanese-friendly font, for all localized screens based on direct user feedback.
Replacing Commercial Imagery
Our original login screen used a Mt. Fuji photo that felt too touristy. We replaced it with friendly, human-centered visuals to match the app’s purpose.
Improved Interaction
Users tried clicking on flag icons to change languages, but only the small button below worked. We made the whole flag clickable for easier use.
Sorting Differences
Unlike U.S. apps like Amazon, Japanese users use fewer sorting filters. We simplified our browsing experience based on that preference.

Water Bottle Design Project
Project Type
Photography
Date
July 2023
Objective: Design a water bottle to meet specific constraints.
Volume: Required to hold 500 mL.
Manufacturing Cost: A primary focus on cost reduction, with the base of the bottle being twice the cost of its sidewalls.
Opening: Designed with a 2 cm diameter.
Approach:
To address the design constraints and achieve optimal dimensions, we utilized the Lagrange multiplier technique. This method was instrumental in ensuring that the bottle met the volume and cost requirements while maximizing efficiency.
