Project Overview
Context
Consolidating investment journeys across Mutual Fund and Provident Fund, including onboarding, account logic, and segmentation architecture.
Challenge
Mutual Fund + Provident Fund were previously separated apps built by Bambu → causing fragmented experience and operational complexity
Outcome
Reduced cross-platform friction and established a scalable multi-product investment foundation.
Structural Gap
Two separate apps (Mutual Fund & Provident Fund) developed by Bambu (Singapore) resulted in a fragmented and confusing user experience.
Strategic Shift
Led the redesign and consolidation of two legacy apps into a unified investment platform in collaboration with a Thai software house.

Usability Testing
Our Usability Testing involved 9 participants with diverse backgrounds in terms of gender, mobile OS, and an age range of 25–55, all holding at least a Bachelor’s degree. We tested core functionalities including App Setup, Onboarding, Suitability Test, Account Opening, and Fund Purchasing. The overall results were highly satisfactory; although some participants took longer on certain tasks, we achieved a 100% completion rate.
