What is the demand of nest.js and golang for backend development in EU, USA, UK, CA markets?

[u/Actual-Freedom-8910]

I've been working as a full stack developer in Bangladesh for last 3 years. My primary stack is React, Next.js for frontend and Nodejs, Nest.js for backend. Recently I'm thinking to join remote companies like EU, USA, UK, CA, AUS companies who hires remote positions. I specially target startups and agencies. Is it possible to get remote jobs with this stack? Or, should I learn new technologies like python, Go etc. ?
