Is my project good enough for CV?

Well, I’m currently a Polish IT student, and I’m looking for a job. Since I don’t have any professional experience yet, I decided to create something meaningful to put on my CV.

Initially, the idea was to build a parser that uses RPN to evaluate expressions. However, over time I kept adding more features: user-defined functions and variables, recursion, short-circuiting, assignment operations, references, local variables, sequential execution, loops, and multi-line input. All of this eventually required building an AST and dealing with a lot of pointer-related complexity.

I’ve gone through several refactorings (I still consider myself a beginner at programming) and even one complete rewrite of the code. I also noticed that there isn’t much detailed information about some parsing topics—at least beyond Wikipedia.

At this point, the project feels more like a very weak version of Desmos (without graphs) than just a calculator. Now I’m wondering: should I continue developing this project further, should I move on to something more complex, or is this already enough for a CV pet project?
