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 tried to break Techcombank customers’ inertia toward investing with Investment Nudge.

It nudges customers to invest, walk them through a simple flow and takes the opportunity to encourage them to form better investment behaviours.

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 Phone Keeper to help customers deal with untidy storage and sluggish performance.

Used and loved by more than 100,000 customers just 4 months since the first release with a rating of 4.4 ⭐️ on Google Play.

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).

I took over the app when Samsung decided to bring it back to the in-house development team. I tested the existing app and improved the design while aligning it with the Samsung design guideline. I documented the very first user interaction guide for the app so that the team could maintain and scale the app more effectively.

Galaxy Gift is a 5 Million+ users loyalty app for Samsung smartphone customers in the Vietnam market (data from August 2018).

I led a team of 3 designers to design this parental control app from start to release.

Family Care allows parents to have a certain level of control over their children’s phones. The idea is that children aged 9 to 15 may have their smartphones, but their parents need to make sure that they do not misuse the devices.
