01
The constraints
- Coordinating a broad modular domain without treating every module as finished
- Maintaining real-time chat state between a mobile client and backend gateway
- Uploading media without passing large private files through the main API
Mobile/API · Broad MVP in active development
Community Platform & Mobile App
A modular NestJS backend and React Native application covering community discovery, profiles, real-time messaging and media workflows.
Generalised from private active-development repositories. No live user base, adoption number or complete-module claim is made.

From constraint to systemDecisions that make
Decisions that make
complex work calmer.
Challenges, implementation choices and resulting capabilities—without converting private work into unsupported performance claims.
02
The approach
- Organised backend capabilities into explicit modules and REST contracts
- Used WebSocket events with local client persistence and connection-aware states
- Implemented presigned object-storage uploads and queue-backed notification work
03
What it established
- Connected authentication, profiles, discovery, messaging and uploads in one MVP architecture
- Established reusable API, state and media patterns for additional modules
- Kept adoption and production-readiness claims outside the public description

Generalised from private active-development repositories. No live user base, adoption number or complete-module claim is made.
Client identifiers, confidential assets, private repositories, commercial data and unverified performance figures are not part of this case study.
