Data, Markup & Patterns | Developer T-Shirts

Formats and syntaxes that keep projects organised, APIs talking, and documentation readable — most of the time. This collection highlights the unsung heroes of everyday development, from JSON to SQL, wrapped in a modern, understated aesthetic.

These patterns often sit between interface work in Web & Frontend and the systems thinking found in Backend & Server, providing the structure that keeps everything predictable and portable.

Every design comes in dark and light, printed on demand.
