Getting something working and out there is 90% of the battle, especially on small or single person teams. I wrote a saas php app with vanilla html and JS that ran without issue for 8.5 years for a fortune 1000 company. About twice a year I would return to it to add or modify a feature and I had no idea how a lot of it worked and even had duplicated or redundant files that I was too afraid to delete. It worked though and I got paid every month for a very long time. Sometimes delivering a product is all it takes and getting trapped in delivering 'clean' code is just a blocker. Not often, but sometimes :)
