I am sick and tired of my enterprise development job, I need some programming direction like this:

• Demanded in jobs-market
• Demanded in freelance market
• Can use Ubuntu as development environment
• Not enterprise. Standalone, mobile, web-development, anything, just not enterprise.

Basically, I need a programming direction which doesn't need 20 developers, terribly big databases systems and long going projects with intense long-term support, I don't want enterprise job where a lot of people are working on one terribly big project and do modules to it all day long.

Instead, I need something where:

• Projects change pretty often
• Projects are little, or medium-sized (in terms of code, modules and people working on it) but still not enterprise-sized
• Possible for freelance, solo-development, or at least requires a team of 3-4 programmers. Not like in enterprise where you feel like a drop in the sea with your 50 classes while system itself has hundreds of classes.

Suggestions please?
