I develop software and systems for a telco in the midwestern USA. I have been developing software for a week or two longer than I have been a member of StackExchange, though I played with static HTML and CSS here and there since the age of 10.
I do a little bit of open source work:
Stack Exchange is not the only place I frequent:
Q&A for professional and enthusiast programmers
Q&A for speakers of other languages learning English
Q&A for peer programmer code reviews
Q&A for meta-discussion of the Stack Exchange family of Q&A websites
Q&A for professional programmers interested in conceptual questions about software development
Q&A for linguists, etymologists, and serious English language enthusiasts
Q&A for professional system and network administrators
Q&A for user experience researchers and experts
Q&A for contractors and serious DIYers
Q&A for users of Linux, FreeBSD and other Un*x-like operating systems.
Q&A for members of the workforce navigating the professional setting
Q&A for database professionals who wish to improve their database skills and learn from others in the community
Q&A for parents, grandparents, nannies and others with a parenting role
