The project was eventually discovered by my (now former) employer who needed the same provider but did some searching before writing his own and discovered my project on Github. It landed me a job interview and eventually a job. I don't think my project was the sole reason I got the job, but was more likely telling them I was operating in the niche they were looking for. Something that probably didn't stand out as much in my LinkedIn profile to be noticed there. Or I hadn't told it to enough people as there was some shared working history with others in the company. Enough to let them know they should hire me, but not enough to tell them I was someone they were looking for.
One of the contributors to the project also ended up at that company, I was asked about him during his interview and could give nothing but praise because I had been working with him on my project.
My 2ct is that whatever you do, make, patch, write, think up of, just put it out there. Even if it is not finished, create a repo and publish it, write a blog post, post it on a social. You never know who is searching for what and will find you that way. Your project , contribution or code snippet doesn't have to become a (commercial) success, if it just helps people or connects you in a way to someone new w're all better for it.
