Thinking about moving to Japan as a Junior Dev?
Don't be fooled by the high salary rumors. The reality for juniors is surprisingly brutal ($25k?!).
But there is a strategy to survive.

I just figured this video is still running great. I assume there is a demand for this kind of videos.

The second FlutterNinjas Tokyo is just around corner. 🔥 The preparing started 7 month ago and it's finally next Thursday.

I'm glad to see the people who comes to Ninjas started coming to Japan 🇯🇵

For me personally, to treat myself, I'm looking forward to drinking at the after party :) 🍻
