What are the best stacks to land full-time remote work opportunities?

Web, vba development – 2 years HTML, CSS, SCSS, Vanilla JS, jQuery, Jekyll, Bootstrap, Sketch UI/UX prototyping and design (not a designer though), VBA

Web app development – 2 years All the above plus EmberJS, LESS Some Python, some Django, Firebase

Have played around with other frameworks but haven't dived too deeply yet

Degrees in English Literature, Info Systems Design

Speak and write English at a fluent, native level Speak and write French at an intermediate to advanced level (did majority of translations, then revised with pro translators for current job)

Worked remotely before and highly productive doing so.

I'm looking for job opportunities for August/September next year and wanted to prepare myself to be a strong candidate. Ideal time zone is east Asia (Taiwan, Korea, Japan). Any suggestions to shore up current skills and any others I should pick up?
