Bill Karwin

I've been a software engineer since 1987, and my specialty is as an SQL maven. I also have experience programming in Java, Ruby, Python, Go, PHP, Perl, C, JavaScript, and I have many other coding skills.

I've written a book, SQL Antipatterns: Avoiding the Pitfalls of Database Programming from Pragmatic Bookshelf, based on the most common SQL problems I've answered on Stack Overflow and other forums, mailing lists, and newsgroups over the past 15 years.
