As someone who has built and shipped lots of projects, both for work/startups as well as personal/side ones, I would say that most of the time with building/shipping products quickly, tons of corners are cut. It may not be obvious at first sight but you could see if you look for it. That's typically how one person can build and ship something in very short time. As a simple example, in HN, tech circles and the software engineering industry we talk about node, react, microservices, architecture design, etc. but when you're one person trying to ship a product, there's a high chance you're writing some basic HTML, jquery and some php backend, rather than a react SPA with SSR/SSG. (Not saying this is how OP did it, just in my experience how I and a lot of others did it) You're also right that it's infinitely easier to build and deploy things in 2020 than it was in 2010!
