So I have been accepted into a small-mid size company for a month. In a month, I've been asked to make an app using a library that I don't know and kinda old / rare to be used. Mind you I spent 1 month developing this and searching also bug fixing the app alone.
It's also my first career in the professional work.
But I feel extremely pressured and confused anytime I'm working and even when I got home. Is this normal? Or should I resign?
No, I don't work in a team. I'm literally solo and alone working on this right now while reporting my work to Chief Technology Officer in my company. I don't even have Backend engineer because I used native android and the library can be used without a back-end engineer (It's kinda like a Router / Websocket or something? so they just installed it on the domain / server and I can use that websocket)
