The market for software development in São Paulo are divided in two big areas, each operating under different "rules". Note that 1 USD = R$ 3
Developers working at advertising agencies make from R$ 1500 to R$ 4500 per month before taxes. You have the odd one making more than that, but they're usually really senior guys in the field. Ad agencies are usually writting bad PHP and tying up Javascript libraries together. Agencies usually jump through a lot of hoops to avoid paying any taxes, or paying as few as possible, expect 0% - 10% taxes at agencies. This tax avoidance/evasion is illegal, but standard in the market.
Developers working at everything else make from R$ 3000 to R$ 12000 per month before taxes. You can find projects with any language and field, São Paulo is a very good city to be for software developers. The other good cities are Rio de Janeiro, Porto Alegre (lots of FOSS there) and Recife (a great scene for Game development). Expect to work legally and pay real taxes here, something like 20% - 32%.
The salaries I mentioned are for working in São Paulo. Rio de Janeiro is about the same, but Porto Alegre, Recife and other state capitals can pay 10%-30% less, working on smaller cities may warrant salaries reduced by 50%.
I started my career working for advertising agencies, but started to work consulting for big Brazilian clients later. Along this route I got a lot of experience and got to see how people work around here, and their salaries etc.
Currently, I work remotely for International companies as a consultant via Toptal. It works great, and the pay is incomparable with the local one, specially due to being paid in dollars.
