Since July 2011, I have contributed substantially to Stack Overflow, which is a "collaboratively edited question and answer site for professional and enthusiast programmers." I have answered over 800 questions. There are over 175,000 Python questions, making it one of Stack Overfow's most popular topics.
Nearly all of the questions I answer involve Python, and many are about "Programming 101" topics, Python syntax, Python idioms, and the Python standard library. Many also cover other tools such as ORMs, the Django web framework, Google App Engine, databases, and regular expressions. Other questions use Python, but are widely applicable to other languages, such as questions about object-oriented programming concepts, data structures, algorithms, optimization, and complexity.
I have included a selection of my answers which show my ability to rapidly solve problems and communicate technical information on Stack Overflow Careers.
