I am a Lead Back-end Software Engineer working at Zalo, the #1 messaging app in Viet Nam. My main responsibilities include, but not limited to, maintaining and improving stability and performance of the back-end system serving 54 million users monthly and more than 2 billion messages daily.
When not working, I usually exercise, swimming and running, to recharge my enery for the next challenge. Also, I enjoy reading books, mostly history and philosophy, to expand my horizon.
