Gantt timeline for Projects
Feature lead
Took a new timeline view from a fake door test to release for all users in about two months. Evaluated third-party libraries, chose a custom build, and kept it fast at scale. Then turned it into a shared component that powers a multi-project view.

Project lead, frontend owner
Owned the frontend of the core deals view and led the project that made the board customizable. Merged two board implementations into one, made large boards fast and modern.

Front and back end
Added source tracking to leads and deals across many services, so teams can see where every deal came from.
Help centre: Lead sourceNote limits
Implementation lead
Added note limits to every note editor, with server-side validation. Wrote a shared library so the limit logic and translations live in one place.
