Is this a scam or this how the tech service industry works

Last September I was hired as an UI Engineer in a startup in Gujurat. This is my first job in tech. They said that you will get to work on client as well as in-house products. My first task was to fix their in-house product, so that they can re-launch it. Successfully did that. Then they started searching for client works. And till now (March) they have given 4 client jobs to work on, none of it was related to Frontend or UI. One was related to AI, another one was related to a Node Backend, and the current one is related to 3D technology. So what should I do now, it almost feels like a scam. Leaving a company in 4 months doesn't feel right but I can't see any learning or improvement here in my domain. And the worst part is this jobs are brought by my CTO fooling the client that the developer who is going to work on this had 10+ years of experience.
