I think it's relatively easy if you work within companies of a certain size. If so, compare yourself to another 100 developers that you've worked with. If you only work with start-ups, it may be more difficult. Questions to ask yourself: - Do you consistently get higher ratings than your peers? - Do other developers come to you first if they want advice on the correct way to do something? - Have you produced features that cause applause in sales teams or customers? - Have all of your products been successful (maybe allowing for slips in schedule or budget)? - Do people understand your code? (i.e. do you get a lot of emails from people asking to explain things?) - Do features that you have created have significantly fewer bugs than other features? - Do tech leads or product managers seek you out to help them build products or features?
