Currently in master branch you can find a general resume which isn't oriented to a specific job position. There are other versions of the resume, with relative branches named after them, for positions such as backend or research. Checkout them with
$ cd resume
$ git checkout <branch-name>
To see all available branches simply run $ git branch -r.
In short, use Overleaf. Copy and paste the content of this repo in a new Overleaf project, then generate the PDF. Be aware that various branches are available in this repo, so choose the one you need.
An Overleaf project has a git link and can be treated as a repository, allowing some comfortable features. For example, when you push modifications, the PDF is automagically rendered inside the relative project's browser page.
