Should I consider leaving my current company?

If you are getting to code handson and getting the pay you want then it should not matter if other person is egoistic or not, you should ignore other than work in office. You can work till 2 years if work Is good. But if you feel that you job is at risk here then surely look for a new one first without Letting anyone know and the if you get any offer, dice wheather you want to shift and switch without a second thaught.
