nurio.kr Nurio
A production booking and payment platform I built and operate, handling paid reservations, capacity limits, waitlists, refunds and operational notifications. Three separate services, each with its own site and app, run on one Rails codebase: nurio.kr for in-person language-exchange meetups in Seoul and Daejeon, study.nurio.kr for learners in small-group English speaking studies, and studyleaders.nurio.kr for the English session leaders who run them. A 1:1 tutor marketplace is built and launching soon.
