As others have mentioned - great choice using left-side navigation.
That being said, I feel as though the side nav section might benefit from a slightly edited structure.
If you get a chance, try dividing content into the following sections:
1. Title: Logo, name, and basic info (position, location, resume link)
2. Contact: "Contact" subtitle, phone, email, social profiles (if you have any... if not, sign up for some!)
3. Case Studies: You currently have a "Portfolio" subtitle and a "UX Work" sub-subtitle both anchored to the same section - this seems redundant (and a bit unnecessary since the right-side isn't too long as is).
I'd have a single, unanchored subtitle with all work indented below (maybe make this a drop-down)
What do you think?
