This is not a postmortem of a failed startup, maybe a failed app. The fact still is that to your consumer the software makes 0 difference. They will never know if you're running php or python, serverless or cloud. It's all a moot point until you hit at least $10k mrr or something. If you are spending majority of your time on these technologies then who is working on getting the leads, sales, seo, and the other little million things that are equally important for success, if not more.
