I've been big on python testing lately. I've implemented testing for large python projects at two companies now, bring them from 0% coverage to 100% coverage. I'm well versed on mocking tools to isolate components for testing, make tests deterministic, and remove the need for networking (who wants to run tests that rely on third party things).
I've been a remote worker for about half a decade now, so I had a track record of getting things done without direct supervision. I'm also available for other work. I'm a generalist with a vast amount of experience working with web technologies. I am capable of doing system admin and orchestration (ansible is my favorite), backend code (I prefer django and tornado) and frontend UI work (who isn't using react nowadays).
