Front-End Web Architect And Gamepad API Lead at Gamepad Tester
Builds the browser test scripts behind Gamepad Tester and keeps them accurate at high polling rates.
Calder is a front-end web architect working with the HTML5 Gamepad API. His focus is the part most browser testers get wrong: reading a controller often enough, and timing it well enough, that the numbers on screen match what the hardware is actually sending. He writes the polling loops that capture analog trigger tension and stick travel without dropping samples, and renders them on 2D vector layouts that hold a steady 60+ FPS on ordinary laptops.
On Gamepad Tester he maintains the main tester tool, the button test and the trigger pressure test, and reviews any answer that explains how a reading on this site should be interpreted.
