You’re a student. Open sourcing the code for portfolio purposes is a good idea, whether or not the code is great.

Entry level engineers on their own are not expected to produce flawless code let alone architecture. That you achieved something that ambitious in the first place will be a mark in your favor for most hiring managers.

Just check your contract and IP agreements first to make sure you actually have the right to use the code, since the way you’ve phrased it makes it sound as if you adjusted the company’s code rather than rewriting it from scratch after your role with them ended.

I definitely own it since it was an "extra duty" project and they never paid for it, nor claimed it, just used it in the early stages that's all.
