Community contribution


I am admin of Ruby-Vietnam, a community of ~2000 developers in Vietnam. From 2015 to 2019, I help Trung Le, founder of the community, organize events in Ho Chi Minh City and Ha Noi. There has been more than 20 meetups and hacknite since then.

Below are a few talks I present at the meetups:


In 2015-2016, I helped GIVEasia, a crowd-funding platform for charity events, as volunteer developer. The most notable feature that I developed there is the recurring payment module.


From 2018-2019, I work on Kipalog, a knowledge sharing platform for Vietnamese developers, to improve performance and test coverage. Occasionally, I also develop new features to improve the user experience.
