Who We Are
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!
