Marina Wyss wrote that piece and the part that stopped me was not the curriculum. It was her argument that a hiring manager is not looking for evidence th
There are three entries in my project's record of what its owner said that the owner never said.

As I continue learning and working in the tech field, I have been learning not only how to build websites and applications, but also how to handle account credentials securely.
