First, the sanctions on Iran are such that any partnership with an Iranian person for business reasons is effectively impossible in the West, without the resources of a multi-million or billion-dollar company to circumvent them. The author says "I am not looking for anyone to bypass sanctions" but that is very obviously exactly what they are asking for.
Second, circumventing sanctions is illegal, and people regularly go to prison or are given massive monetary fines for this. OP, I don't question your motives, but you need to understand that people have literally gone to prison and lost their whole livelihoods for doing exactly what you are asking.
Therefore, posting this on a Western platform (Github) and advertising it on a Western message board (HN) is unlikely to help. I don't think the author's intentions are poor; I think they may simply not understand the intensity of the legal regime that makes working with them impossible.
There is also the matter of Westerners' general opinions on Iran, which - general attitudes of multiculturalism and tolerance nonwithstanding - is typically quite negative. The sanctions didn't come from nowhere.
I would recommend the author look into partnerships with persons from countries that are more sympathetic to their situation. The ones with strong tech industries would be Russia, China, and India. Vietnam is another example of a country with some tech industry which also has mostly positive relationships with Western countries, these days. I realize this is not as attractive as the West, but there are good people even in places whose governments I may as a Westerner may not particularly like, and English is a lingua franca the world over. I'd strongly recommend those places as a starting point.
