hello r/DnD. I need some help with my lvl 7 Rogue. [Pathfinder]

So I am playing a Hafling Archer Rogue but he is focused more to utility (disable device,acrobatics,bluff etc etc) and I can do sh*t in fights. I don't want to play with the Improved Faint cause I cannot find it realistic for a range rogue. Atm I have rapid shot, empower shot focused shot for fight feats. So I am thinking if I there is a prestige class which is focused @ abilities / utility or is there a good class combination which can gimme same good fight skills.

Edit : correcting feat.
