Bringing essential electricity services closer to customers across Vietnam.
About project
EVN CSKH is the official customer service app developed by Vietnam Electricity (EVN), serving customers across Vietnam. It brings everyday electricity services into one place, from managing electricity contracts and tracking consumption to paying bills, reporting issues, and receiving service updates.


Project overview
One priority was making electricity usage easier to understand at a glance. Customers needed to see how much electricity they had used this month, how it compared with last month, and where to go for a closer look.
What I did
As a freelance Product Designer, I worked with EVN stakeholders to set priorities and designed more than 20 flows for existing and new features. On Home, I showed monthly usage alongside a comparison with the previous month and a link to the detailed breakdown. I also built a reusable design system for developer handoff. Within about five weeks of the pilot launch, more than 1 million customers across Vietnam linked their accounts.
