I’m a developer who cares about the part of a website nobody screenshots: the timing. I build sites where motion is measured, not guessed, and the tools that measure it.

Study one reference deeply and reuse its measured values. Borrow one gesture from a second. Make the rest from the subject itself, then check every transition frame by frame on a laptop and a phone.

Vite and vanilla JavaScript, WebGL written by hand, GSAP and Lenis when they earn their weight. Python, Playwright and SQLite for crawling, capture and testing. Claude as the builder inside the loop.

Studios, founders and teams with a motion-heavy site to ship, or a design process to automate: write to [email protected]. Code on GitHub: cosh03.
