I'm sorry, but you are being paid by Portuguese standards (you sure it's net 22.k USD, not €?). I have received some offers for jobs in Amsterdam, the highest was 450/500 € per day, and I believe there's similar offers.

You're comparing a consultancy rate (of which you'll be lucky to pocket 20%) in Ams with a salary in SF.
