Good on you!
First impression – I like the clean simplicity.
I think the quickest and easiest improvement that you could make would be to get someone to do an English edit for you. You are communicating your message well, but there are some basic mistakes that could be quickly sorted.
Your projects are clearly laid out and I love how you describe your process, but some of the sections feel a bit light.
There are a few strange layout inconsistencies in your travel app project that make it a bit hard to follow (the personas section in particular).
In summary – this has great bones but could do with some refining. 2 projects is a bit light also, but it's a start.
