My work with Mathematical Sciences Publishers is remote, giving me ample opportunity for various freelance jobs. I have written reviews and edited books, articles, resumés, and theses. I give private classes in mathematics to Leaving Certificate and first- and second-year undergraduates. I have also done some mathematical and computing consulting.
I have varying levels of experience in Latex, Python, Perl, HTML, bash, VIM, javascript, C, GAP, Matlab, MySQL, Windows, Linux.
See, for example, my page on Upwork, which can be an interesting site for finding freelance work.
If you need any editing done, want some assistance with mathematics, or have an interesting problem -- drop me an email.
