Which programming languages are the best for remote Job?

#-Link-Snipped-# - welcome to CrazyEngineers. Remote jobs aren't language dependent. My best guess is that you want to get into freelancing. If that's the case, you should be offering services in the languages or tools that you are most comfortable with. 

I've seen steep rise in the remote jobs that directly or indirectly involve JavaScript. JS has been growing in popularity and so are the remote jobs. If you can build skillset in Vue, Angular, Express, Node et.al.; I'm quite sure you'll find lots of clients who are willing to get their products / services developed remotely. 

Another strategy is to develop skills-set in relatively less popular technologies. The advantage is that you can command better hourly rate. But it could be time consuming to build expertise in these technologies.

In general, you should aim at building a solid skill-set in any technology or framework of your choice and then aim at getting 5-star ratings from your first customers. That'll help a lot.

Another way to make money online is through blogging. It requires writing skills more than technology skills; but most popular blogging platforms are built using PHP. 

I've seen lot of freelancers offering PHP development services specific to blogging software like WordPress, Drupal or Joomla. That's something you could explore as well. However, be aware that while there will be plenty of jobs; the competition will be greater as well. 

Which tools or technologies are you expert in?
