I like software development, particularly web development / coding, good software engineering practices and principles, databases, algorithms, problem-solving and software architecture.

In my opinion, Stack Overflow is a great technical knowledge repository for those of us who often come across technical problems and doubts.

The end of all software development is to serve people and be of any use, be it commercial, academic or just fun. To accomplish that for the projects I get involved I try to keep updated and improve my technical skills, since to have a good result I believe we have to understand the inner details of what we are doing or what we could do to improve it. Can't deny that Stack Overflow is good tool to help with this.
