But those two statements seem to me to be very different. The first would make you a web backend developer and the other more of a network engineer or sysadmin. I know this probably isn't too different for many people, but those people won't probably be able to imagine a specific job if given either description.
I don't want to be just negative, so I'd like to suggest an alternative: "I make parts of computer programs, like <names of well-known products that are similar to ones you make>". This will be easily understandable to everyone who knows what computer programs are and also won't be misleading. You could also add "for the internet" somewhere if that part is important.
