What info did you give your boss to justify a raise? If you just say "I want a raise" that is unlikely to be effective. But if you give them data, like "x number of new features implemented in the past year", "x long-standing bugs fixed", or "x% of commits passed testing the first time", that's more concrete and something they can both compare against your peers, and give to their boss as a way to open up the money spigot.
