normally I do not comment personal sites and online portfolios, because of the lack of context and because of the lack of knowledge about the design skills of the site owner.
As soon as I started to browse your site I was impressed by the way how you tell us how you work and what is your design process.
What u want to achieve with your site?
Do u want to find a new job?
Do u want to publish what you are doing as a designer?
I don't have any relevant feedback in terms of look and feel, the only thing I'm missing from a UX portfolio is the prototype and the test steps.
I didn't read all the projects, so maybe I choose the "wrong" ones.
I hope it will help
