I've only ever "shipped" two independent projects, and they are the the best things I have ever done for myself in terms of development, both from a personal career growth perspective but even financially.
I work at a nonprofit and I had done some ABSURDLY SIMPLE data analysis on a relatively annoying public data set to consume. I'd done it for our institution, but it was sort of straightforward to generalize it to any institution for which this would be applicable. The code was... awful. Rather than doing it "properly," since I already had all the code I had written to do the analysis for my institution, I literally just ran it on the entire data set (10GB or so) for every organization that existed and then just put some result file on S3. My "site" would just let folks search for their institution, and present the data with a couple graphs, some nice visuals, and have them print it out. I was ashamed of it in a technical sense.
But I just bought a domain and tweeted at a journalist. Whelp, two weeks later, I had my picture in the city's biggest paper, my org got some positive press, did a service for other non-profits, had folks reaching out to me about jobs, etc. It took SO LITTLE effort, and every instinct I had was that it was bad and I shouldn't publish it. But the reality is I had already done 95% of the work... committing to just do the extra 5% was so hard to do, but in hindsight, so obviously amazing ROI, even if it hadn't gotten the attention it did.
Secondly, I built a reading app for a teacher at my school to let him do an activity where kids would jumble up sentences and paragraphs in order to help them understand transition words. The only reason I agree to try to do this was that I was learning React at the time and wanted to play with the React drag and drop library. After a weekend, I had it essentially working, and it was a success in his classroom. And here, too, it was to be the end of it... but I pushed myself through it, added a simple login mechanic, user account, etc. I had a small technical question as I was wrapping up, and I posted it on reddit. Someone who worked at a nonprofit mentioned to me that the app could potentially qualify for a grant that the Verizon foundation was running for learning apps. I applied... and we got it. The money award helped pay for my entire grad school tuition.
Really... just ship it!
