How this site is made.

A brief note on the tools, decisions, and principles behind every pixel of this portfolio.
/ˈkɒləfən/ — a brief statement at a book's end detailing its production. A publisher's colophon, adapted for the web.

This site is built with NextJs, deployed on Vercel, and designed in Figma. It even runs "green," producing just ~0.07g CO₂ per visit.

Craft notes

Design principles

Typography first

Playfair Display for display headings, Inter for body. Hierarchy is everything.

Sustainable by default

This site produces ~0.07g CO₂ per visit — cleaner than 90% of web pages tested.

Accessible

Semantic HTML, ARIA labels, keyboard navigation, and sufficient colour contrast.

Performance obsessed

Static pages, optimised images, and edge caching keep load times tight.
