Ask HN: What's your personal website's tech stack?

I want to spend some time this weekend re-doing my site (www.garysahota.com) in a platform other than Google Sites. I'm learning web dev now and would love to get your thoughts on what tech I should use!

My requirements:

- Minimal cost (free via Github Pages or the like if possible)

- Semi-frequent blogging

- Static site

- Mobile ready
