I'll be releasing an updated and more in depth post about this soon.

Arneelus Lewis I’ll review your resume if you’re comfortable with me sharing the review on my YouTube channel.

It's always pleasant to see the portfolio on some web page rather than document. Its easier to consume, scroll by and get the first impression of the person. Having a dedicated website shows commitment ( not sure that that's the right word ), the level of how serious you are regarding your services. So yes, that is an investment that most of us take at some point. Also, make sure that your website contains SEO for the services that you provide, web development in your case. My suggestion is to make one and ask for a review, and you can change 'needs' to be changed.
