There will always be people who are negative about X, Y or Z. Find your own way. If you start believing them that is trouble because it'll come across in any interview.
Be proud of the time you took out to travel around Asia. "I had a fantastic time, learning about new cultures, broadening my mind, meeting new people from all over" etc. On top of that you were resourceful enough to pick up projects/freelance work over that period. Many people will be jealous of this. Speak to this part of them.
Not sure if you had prior experience or just graduated. Either way I would put it on your resume along with your travel. Something like:
2017 - Travel around Asia while freelancing. Here's a list of freelance projects I worked on: - Sysadmin running servers.
2014-2016 - Software engineer, Midwest city - Regular software job
