Community & networking platform
The challenge
Communities coordinated across unstructured chat groups where information disappeared and newcomers could not find services.
A digital platform connecting people, communities and opportunities to reduce fragmentation in communication, networking and access to services.
Our role: Full-stack engineering and real-time systems
Architecture decisions
Document model for flexible content
MongoDB lets posts, events, services and groups evolve without migration churn as the community defines what it needs.
Typed contracts end to end
Shared TypeScript types between the Express API and React client remove a whole class of integration bugs.
Feed built for slow networks
Paginated, cached feeds with optimistic interactions keep the app usable on 3G.
System architecture

- 04DataMongoDB with compound indexes on feed queries
- 05OpsRate limiting, moderation queue, structured logging
Results
Communities gained a durable home for conversation, events and services instead of losing everything to chat scroll.
