Your challenge, if you wish to accept it (and we sure hope you will), is to optimize this online portfolio for speed! In particular, optimize the critical rendering path and make this page render as quickly as possible by applying the techniques you've picked up in the Critical Rendering Path course.
To get started, check out the repository, inspect the code,
Some useful tips to help you get started:
- Check out the repository
- To inspect the site on your phone, you can run a local server
$> cd /path/to/your-project-folder
$> python -m SimpleHTTPServer 8080- Open a browser and visit localhost:8080
- Download and install ngrok to make your local server accessible remotely.
$> cd /path/to/your-project-folder
$> ngrok 8080- Copy the public URL ngrok gives you and try running it through PageSpeed Insights! More on integrating ngrok, Grunt and PageSpeed.
Profile, optimize, measure... and then lather, rinse, and repeat. Good luck!

- Measuring with Navigation Timing. We didn't cover the Navigation Timing API in the first two lessons but it's an incredibly useful tool for automated page profiling. I highly recommend reading.
- The fewer the downloads, the better
- Reduce the size of text
- Optimize images
- HTTP caching
The portfolio was built on Twitter's Bootstrap framework. All custom styles are in dist/css/portfolio.css in the portfolio repo.

Open the page in Google Chrome or preferred browser and navigate the sites.
- Added an internal style sheet for index.html
- Made all scripts asynchronous in html as the google analytics script was making the page load very slowly.
- Made all images as small as possible, as close to the size being displayed on the page as possible
- Applied file optimizations for all the images
- Added will-change: transform; to class .mover to make each pizza in the background an individual layer and found speed increase of approximately 0.2 ms
- Removed calculation of phase from for loop which removed forced synchronous layout
- Removed function determineDx and replaced with percentages for pizza size changes, also removes the issue with forced synchronous layout for pizza size changes
