I'd actually go so far as to say a "certification" could be a net negative on a resume applying to a software shop. At Microsoft, Google, Amazon, or startups run by folks from companies like those, there's definitely the attitude that if you need a certficate, then you can't really program, and if you actually can program, then you don't waste your time on certificates. Certificates are viewed as something a technician gets, not a "real" computer scientist or software engineer.

It doesn't really matter whether this is a good or valid or accurate view of those who get certifications. What matters is that this attitude does exist among your potential peers -- at least as those kinds of companies. If you want to work in software at a different kind if company, then YMMV.
