Staff tooling for a US education foundation that runs workshops and scholarships: enrolment, rosters, attendance, assignment grading, scholarship applications, donors. Students never log in — every form they touch arrives as an emailed link, which kept a whole student-facing auth system out of scope. I led the frontend and built most of the staff workflows, including a drag-and-drop builder that lets staff lay out a workshop’s curriculum themselves and forms that take their custom questions without a developer adding fields. On the backend I owned the referral module, so registrations coming through a partner’s link are trackable end to end.
