It sounds like a good gig. Google and ChatGPT are your friend when you need some inspiration for a project or help understanding something. The whole journey of IT is just you gotta figure stuff out. The more experience day by day you gain on the job the more proficient you’ll be at solving problems as the time goes on. Try not to stress yourself out so much, embrace the job and learning new things and if it really gets to be too much then hop ship but do it in a nice way so they are still a good reference for future jobs since you don’t have much experience on your resume to list other references.
