Mission

A social media app for events: create them, invite people, and let attendees vote. Built in Buea with a co-founder, released around September 2023, and retired in 2025.

For whom: event organisers and their crowds. Constraints: two people, a self-hosted backend, and app-store review cycles on both platforms.

Decisions

  • Node/Express with MongoDB and Redis first, NestJS later. Shipped on the fast stack, then rebuilt the backend on NestJS once the product shape was clear.

  • Self-hosted with GitHub Actions CI/CD. A VPC we controlled, deployed on every merge.

  • Bare React Native to Expo. Migrated over four months to stop losing weeks to native build churn.

500+ downloads across Google Play and the App Store. Retired in July 2025; the lessons went straight into KwikNkap and Vertex Reader.

What broke

Native builds. The app started as bare React Native, and every library bump meant hand-editing Gradle and Xcode projects that only one of us could run. Releases slipped for build reasons, not product reasons. The four-month migration to Expo fixed it, and I have not started a bare React Native project since.
