I asked this question to the HN community for a little more than a year ago (https://news.ycombinator.com/item?id=21024041) but since technology moves fast and I think it's interesting to hear the answers I am now asking again.
Companies of one is companies which consists of one person.
TLDR:
What is your tech stack?
Why did you choose it?
Do you think your choices had any impact on your success?
Thanks in advance!
