I'm a software engineer turned self-funded founder. The amount of stuff that's critical to early success and has absolutely nothing to do with technology really puts decisions like what stack to use into perspective.

Rewriting using another stack is N weeks/months that I'm not spending on writing, distribution, iterating on paid marketing, cold emails, calls with customers etc. I used tech that I knew I could scale into 1k users, likely more around 50k but we'll see. I've had zero technology based regrets aside for attempting to use Firebase for something that it wasn't suited for early on.
