Assuming your workmates know your skill levels why don't you talk to them. There are lots of different approaches and, right or wrong, you are better to fall into step with them. There is "best practice" and then there's "good enough for the client's budget". Given you sit alongside real developers for 8 hours a day it seems bizarre that you ask here
