Meetio - an event platform from zero to 2,200+ users

Organizers in smaller cities run events on spreadsheets, WhatsApp groups and paper lists at the door. Meetio replaces that with one place to sell tickets, check people in and see what actually happened.

It is multi-tenant from the first table: every organizer gets their own workspace, roles and data boundary.

Meetio is a Turborepo monorepo with shared packages for authentication, database, email, storage and the REST API, so new surfaces reuse business logic instead of copying it.

Next.js App Router on the front, Prisma and PostgreSQL underneath, with schemas, authorization policies and REST APIs designed for production-scale multi-tenancy.

Over 25 email workflows — registration, reminders, ticket delivery, post-event follow-ups — run on Cloudflare Workers and Queues with AWS SES, processed as microservice-style events rather than inline requests.

2,200+ registered users, QR check-ins running at live events, and CI/CD workflows that make releases boring in the best way.
