On September 28, 2026, Colorlib released a compilation of 24 examples of data science portfolios after reviewing 113 websites. Each portfolio represents an individual’s personal site that highlights their recent projects, omitting any inactive or redirected links. Among those featured are Aditya Ranjan, Harrison Jansma, Nicola Rennie, and Marcos Saade. The guide emphasizes the importance of addressing business questions, providing links to code and demonstrations, quantifying outcomes, and ensuring that work remains up-to-date. It also reveals that the most frequently used platform was custom-coded sites (8), followed by Quarto (4), and Jekyll, Hugo, and Next.js (3 each). Notably, 14 out of the 24 portfolios are available for free on GitHub Pages.
