Median LA developer salaries on full time basis (https://teleport.org/cities/los-angeles/salaries/) seem to be 66k for web developer (for the lack of FE in taxonomy) and 78.7k for software engineers in general.
Without knowing your personal tax situation it is hard to deduct your net hourly income from this - so probably more useful to discuss and compare gross (pre-personal-tax) billing rates when trying to understand the market?
