I run DaniWeb. I coded (and currently maintain) the site from scratch using PHP/MySQL/jQuery and grew it into a thriving community of over 1 million IT professionals and 10 million visitors a month, making it not only one of the largest social media websites in its niche, but one of the largest publications on the web to date. I sell advertising. I host annual events throughout Manhattan during Internet Week, Advertising Week and Social Media Week which each see an average of over 1000 attendees. I host a bimonthly meetup group for techies on Long Island and eastern Queens. I speak on panels at search engine conferences.

I'm a super-geeky programmer with a passion for Internet marketing. I am not for hire.
