I develop business-oriented web applications in C#, Java, and HTML5. I build database solutions in SQL Server 2008-2012 and Postgres 8.2-9.1 (and some MySQL 5.2).

I am not an expert, but I am a professional.

The best solution is the one that satisfies the requirements at hand with simplicity, elegance, and extensibility.

The right answer is always "it depends."

Know thy customer, know thyself.
