I was a global top #10 user on Stack Overflow, the world's #1 programming Q&A site, for more than a decade

I authored 7,000+ answers across the PHP, JavaScript, HTML, CSS tags and many others.

I also spent a lot of time and effort on the site's Meta, authoring policy and UI suggestions to help create a friendlier and happier culture.

Some good answers I've authored
