Working as a ghost developer

Hi viners, I am a 23 pass out and I joined an organisation from my college placements, which is a startup in a metro city which works on web dev and web3 domain basically. So in the first 6 months of my internship, I got some exposure of frontend, web3, solidity and then gained interest in backend. Later on when I got full-time offer, was deployed on a US based project where I am working on the profile of a 9 years experienced node js developer as a ghost developer since last 8 months and it has been smooth so far, I have handled most of the things and I am performing well, my manager is also quite impressed with me there but I am not seeing any personal growth or professional growth working there as it has reached kind of a saturation and I am not learning anything new. So, please help me out with some suggestions if you have any? And also now I am a 1+ years experienced full stack dev with knowledge of web3 and blockchain stack, so any job reccs will also be appreciated, as my priority is to switch as early as possible
