I'm a big fan of sharing knowledge and trying to help people new to a field. I've made this offer quite a few times, with few bites but, are you a new or junior software engineer?
If so, and you want someone to give feedback or do a code review or two, feel free to reach out.
I won't look at a company's code, but your personal stuff? Sure.
My background is C# for the last 2 decades, so that covers Javascript, Java, C#, etc.
Can do professional CRs (more nitpicky) down to just hints...
