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 Volume 1: Avoiding the Pitfalls of Database Programming from Pragmatic Bookshelf, based on the most common SQL problems I've answered on internet sites, mailing lists, and newsgroups.
