Are there any good guides on how to go about this process? I am specifically looking for logistical issues like registering a company or creating a bank account etc. to begin with. But then also tips from other founders on how to handle pre seed or seed stage of the company.
Bonus: If anyone has successfully done this being a non citizen, any tips/guides related to immigration would be very helpful.
You might want to go that way, but as you said "build", not "sell", you may value the approach of bootstrapping and taking a strategic view (e.g. following your convictions).
But you don't need to create a bank account or register a company! You're already a business (sole proprietorship). Go build things :)

Good TLDR to start from is "From idea to paying customer" in Linen blog[0].
