I like your profile. It’s nice and responsive and your code is logically laid out. I especially like that you have your own hosted domain. Adds to the credibility. The only thing I would fix is the hover images before the check out media links section. It’s a little hard to read the text. as the images have text behind them.
When I’m designing sites for clients I like to follow the PSD to HTML template work-flow as I have a lot of experience in design. For source material, freefrontend.com is a great resource for inspiration. I typically don’t use much of the code from there other than for inspiration in building and designing my own components.
I must warn, even though the trend is not to reinvent the wheel I’ve found out that many source materials break in unexpected ways which take a long time to fix. What I do is I build my own components and keep a library or UI kit that I test continually to make sure it works on all major platforms. My site is using a few of those components that I built using the conditions laid out in googles material design. It’s also the reason why I redid my portfolio three times already. Because I used some popular framework which turned out to be too much trouble so ended up using custom code. That isn’t to say popular frameworks aren’t any good, after-all I used bootstrap 4 in my project, just be careful of where it works and doesn’t work.
