is the work experiance the most impressive thing about your CV?
(it shouldn't be at the top if it isn't)
the positions of trust / volunteering is
i would try put that at the top with IT skills and language skills. I would also try to fit more buzzwords into the IT skills section and make other details smaller (e.g. listing gitlab, github for git should take less space after the initial statement that you can git gud)
so being awesome with privacy guides + fineas + (Pirate party responsibilities (maybe avoiding political parts for that moment and just focus on responsibilities) then It skills (that are relevant to the job you are applying for) then langauge (if tha'ts also relevant to the job) then all the other stuff at the end
then the person who reads your CV will think you are aswesome before they read the experiance is a bit lacking
professional experiance, because these voluntary things are more valuable
Also, cover letters are worth a thousand times more than the CV if the right people will read them
you have to be genuine though
like the feneas.org shit is way more impressive than anything else
so slap that slam dunk at the top
