Hi, I read through your description and I can understand you're trying to integrate your backend API to work with your VueJS 3 frontend, not an issue. I have 3 years experience in software development using modern frameworks which includes vuejs, reactjs, axios(for API consumption) and python + django as RestAPI for backend, on any VPS platform using nginx and apache. All my past projects are based on vuejs + RestAPI for backend, I can get this done in no time, and you get your efficient application ready for deployment. I look forward to working with you.
Regards,
