I designed this first product for behavioural change at Techcombank. It was a great effort to drive change in the bank for this new saving product despite restrictions from the State Bank for a proper saving account.

Savings Goal aims to help customers build a saving habit by setting up a goal and engaging them to save regularly.

I was a key designer shaping the 3rd and 4th generation of VOS - an Android overlay run on Vsmart smartphones.

I maintained the compatibility of the Settings app and the Launcher app while other designers added more apps and features to VOS.

VOS 3.0 and VOS 4.0 were developed on top of Android 10 and 11. More than 1 million Vsmart smartphones had been sold with these versions of VOS.

I designed this app to provide Vsmart customers with an extra layer of protection. The app allows users to lock and hide apps on their phones.

It has more than 1 Million downloads from Play Store (the latest update in July 2021).
