Like others have mentioned, this in particular is hard to evaluate without a. source code, b. demo login. Otherwise, all I can glean from this is that you know how to make landing pages :P
But I wanted to point out some design issues I found in your sites. This may or may not actually affect your candidacy, but I thought you should know about them in general as it might signal a lack of attention to detail:
a. Ex: https://i.gyazo.com/205c90719b7e16c19d29fba8b27006c9.png - the error messages are unstyled.
b. Ex: https://i.gyazo.com/fa23a197fa0adb4f8fc0a9aa88ae3797.png - the error message here is too small for me to read.
c. Ex: https://i.gyazo.com/fa3dcbe0c61735b8f958d4d556f57526.png - This is nearly impossible for me to read.
Basically this would signal to me that you're likely not too design-inclined and I would probably focus more on your backend abilities (if given source code). These would be red flags if you were applying for a position that involved design or UX though.
