after a lifetime of web development [started in 1996], you should ask yourself "can i build a full product". if the answer is yes, don't sign contracts and start your product. employers don't pay what you're worth. you can save them 250k in a 2 week period and they won't know you did it and definitely won't pay you like you did. they might even toss you to the side thinking "oh my nephew makes websites". you might have just increased your client's conversion rates by 3% because of an issue on the checkout page and when you call to report on it they might say "oh wow that must be the advertisement i bought without telling you".

in most cases, its too technical for them to understand. i recommend avoiding employers if you're money motivated.
