For convenience I use Elastic Beanstalk to host all my sites.
Most new projects I start are written in Go.
I use nginx as a reverse proxy.
I use Dropbox as a backing store for photo sites, due to the simplicity with which I can add photos from any device.
Several of my sites are pretty simple or use Word Press.
All my sites are packaged as Docker containers, to simplify deployment and local development.
Source control and hosting for my private and public projects.
My blog runs on WordPress, but these days I mostly use it as an automatic aggregation from other networks. My writing—for obvious reasons—is all on Medium.
Where I work. Where I write.
I use IFTTT to pipe posts from Instagram, Google+, and Medium to my WordPress blog.
