Who We Are

Adam

Hi! I'm Adam, the person behind JS Chimp.

I make web apps and software (especially with PHP/Laravel).

I've been on both sides of the hiring equation.

Sent on interviews that didn't match my skillset. And recieved candidates unrelated to what I hired for.

Let's fix that.

Here companies and developers can connect around Javascript, JS Frameworks ... and other tech.

If you've got questions, hit me up!
