I've been applying to jobs for months now as a junior developer, and I have not gotten a role. what can I do to get better chances and land a job ?

I'd appreciate a professional review on my resume and portfolio, a critical review will be well appreciated !

I am currently contributing to an open source project called Water The Trees, at the code for san Francisco community. water the trees is a platform that crowdsources tree mapping, planting, and maintenance.
