Context
Open Mat is one of China's most-followed BJJ and grappling agencies. The media arm produces event coverage, athlete interviews, and competition replays; the community arm runs open-mat sessions and seminars around the country. The business needed a home base that the team actually owned.
What I built
A three-surface platform. The media CMS lets editors publish long-form articles with custom hero art and embedded fight clips. The events module handles the full lifecycle: publish → RSVP → capacity waitlist → QR ticket → door scan → post-event gallery. Membership ties it together: paid members unlock replay archives, early event access, and discounts, with Stripe handling Visa/Master and a WeChat Pay adapter for domestic flows.
Decisions worth calling out
Video sits on Aliyun OSS with edge caching inside mainland China — anything else would be unwatchable. I used Prisma with a carefully migrated schema to keep the database the single source of truth across surfaces, then added a lightweight job queue for email/Wechat notifications so the team never sends a manual RSVP confirmation. The CMS ships with a mobile editor because the team posts from events on their phones.
Outcome
Launched with the team's full back-catalogue migrated and the first three paid seminars selling out through the platform itself. The content team reports a real shift: they now publish *to* Open Mat first, then cross-post, instead of scattering across channels.
