I have a profile on GitHub and I want to say that there is nothing special or extra-ordinary in my code. My code is not simple but there are small examples, and not real big projects. So I want to say "My profile on GitHub is ...". Can I say "my profile is modest?" Or is there a better way to say that? It's a direct translation from my native language, so I'm not sure that it's the same in English.
...there is nothing special or genius in my code
You are only being modest if your code is actually special or genius, otherwise you're just saying what it is.
My profile is modest
Technically means your profile, as an entity, does not use flowery language or hyperbole, but is unpretentious, the low-key attitude does not reflect on your code base.
For example, you are responsible for the latest whiz-bang app that has gone viral, and your profile only says
Your profile is modest(small amount), only two words
You are being modest(understated), since you are much more than just an ordinary programmer
You are being modest in your profile
From a colloquial usage standpoint, if you say
My Github profile is modest
most people will probably understand it to mean
My Github profile and code base is unassuming
which is what you intend to mean since profile can be both the entity which is a summary description of yourself and what your presence on Github looks like
