I'm not sure I see the pain point of being a non-employee Indian developer for someone who's already working for a foreign employer.
As a consultant, a developer can file their income tax return under 44ADA and save a huge amount of income tax, compared to being employed by you and mandatorily paying much more income tax as an employee.
Thanks. You are right in saying that you can save tax with 44ADA.
But it has an upper limit of 50 lac and you have to get a GST number. There are other things as well except taxing. But again different things might matter more or less to different people.
