I have been living in Bali on and off since 2014. From 2015 to 2018, there were frequent IT meetups that were highly technical, no bullshit events that can be seen often lately :) Those meetups were cool and I met some interesting people but guys who used to organize it lost interest or moved out. 

If there are enough WIP members in Bali, we could arrange a similar casual meetup over coffee or drinks.
