Optimizing for the Future: Upgrading My Site with Next.js 14, Tailwind CSS, and Vercel

Three years after building my original website using Next.js 10, styled components, and AWS Amplify, it was time for an overhaul. With experience in Tailwind CSS from other projects, I was eager to apply this knowledge to my personal site.
