PROFILE
Maxim Cheremisin
Max Cheremisin contributed to the contentful/experience-builder repository, focusing on automation, editor reliability, and layout stability over four months. He enhanced code review automation by refining review triggers, reducing unnecessary assignments for dependency updates. Using JavaScript, TypeScript, and React, Max addressed complex DOM manipulation challenges, such as correcting mouse coordinate tracking within iframes and improving canvas geometry reporting by leveraging image load events and multiple DOM rect sources. He also implemented media layout shift detection with ResizeObserver, decoupling media resizing from general DOM mutations. These efforts improved review efficiency, editor accuracy, and cross-browser layout consistency, demonstrating thoughtful, in-depth engineering.

May 1, 2025In May 2025, the team focused on stabilizing the visual/editor experience within contentful/experience-builder by addressing a critical iframe-related mouse interaction issue. A coordinate tracking bug caused by horizontal scrolling inside an iframe could miscalculate mouse positions, impacting editor precision. The fix adjusts clientX with the iframe’s horizontal scroll offset to ensure accurate mouse move events in the editor, improving user experience and editor reliability. No new features shipped this month; the emphasis was on correctness, stability, and reducing edge-case errors in the editing surface. Commit reference documented for traceability: 0515759b2e46e485fc85f00dc305864dae8ee453 (fix: [SPA-2694] consider iframe horizontal scroll when sending mouse move position (#1118)).
