Core Web Vitals explained with GIFs

Passing your Core Web Vitals and google will reward you with visibility. With Google’s June 2021 update Core Web Vitals (CWV) will become a factor in SEO ranking.

Pimp Your GitHub Profile with Books You Read

Keep the books you read in sync with your GitHub profile README In this post I’d like to show you how to use GitHub Actions to automatically sync your Goodreads books you read in your GitHub profile README. I created goodreads-profile-workflow for devs that love to read and like to share what they read.

Useful Npx Packages for the Developer's Everyday Life

Npm comes with a neat tool called npx that lets you directly execute packages from the npm registry.

I focus on packages that have helped me through my daily life as a developer.
