I considered Shopify (I understand I could use whatever tech I want to build them provided I use their API) and even Chrome Extensions. Thank you for mentioning this.
I don't want to get into too many details but basically it will be when I must leave the country. Having established a source of independent income would significantly affect my lifestyle back at home.
Thank you very much. For web stacks, I was thinking Django, Rails, or alternatively Svelte plus REST API written in Go or FastAPI. Any thoughts on that in light of the solo aspect?
