3: Are they in love with a particular technology?

Software developers can fall in love with their favorite technology; it's not uncommon to see developers who only develops with Microsoft or Sun technology, for example. A professional software developer, though, focuses on benefiting his client, using whatever technology is necessary. You want to hire someone that will use the technology that's best suited to your business, whatever it may be. You shouldn't have to pick a developer based on what technology he's familar with; he should be able to take care of almost any technological problem, either by doing the work himself or outsourcing to someone in his network of contacts.

4: Are they charging by project?

Amateur software developers tend to charge for their time, not by the value of the work they perform; so do contract programmers. Real software developers, though, charge based on value provided to you - by project - NOT based on time. This is because amateurs are afraid that they won't be able to complete the project in a reasonable amount of time, so they want reassurance that they'll be paid for their time in any situation. Experienced software developers, though, are confident in their ability to deliver code under their estimate, they are confident in their ability to provide value, and they that they can provide value that's worth MORE than their time is. You shouldn't be making an investment decision every time you consider calling your software developer.

That's it. Ask these questions studiously, and you'll get a programming dynamo. He'll be able to handle the tough questions and give you the tough answers, and you'll get bulletproof software.
