Gaurav TiwariFounder, Gatilab

Hi, I’m Gaurav.

I’m a developer, publisher and educator, and the founder of Gatilab. My work connects the website, the content and the tools that keep it running.

My background is in mathematics. I like getting to the assumptions behind a problem before choosing a tool or writing the first line of code.

What gives me a kick is making something other people can use. That’s the thread connecting the plugins, the books and the practical guides on this site.

Let’s Build It Properly.

Need a website, a custom plugin or help untangling an existing setup? I work across the code, design and content that make a site useful.
