04✦The stack
Headline tech, nothing fussy.
A deliberately focused stack — the kind a senior team can actually run in production.
Mobile
Flutter
iOS + Android from one codebase — the viewer app.
Backend
NestJS microservices
Service-oriented backend, scaled independently.
Admin
Next.js
The internal admin & content panel.
Hosting
Google Cloud
Kubernetes & autoscaling.
Delivery
Cloudflare
Streaming, media storage & CDN.
Data
PostgreSQL
The system of record.
Headline technologies only — the discipline is in keeping it this short.
05✦Architecture
Two planes, kept distinct.
The API plane handles app logic; the media plane never touches it. NestJS microservices behind the edge — Cloudflare carries the video.
