Privacy first. People always.
A full social platform — feed, messaging, notifications, search and analytics — with native mobile clients and a Go backend.
Challenge
The problem.
A social product is not one feature — it is a system: feed, posts, messaging, notifications, search and analytics that must remain consistent as usage grows.
The bar was a platform that native clients can trust day to day, with a backend that stays operable rather than opaque.
Approach
How we approached it.
01
Service-oriented Go backends
Domain services have clear boundaries so the stack can grow without collapsing into a monolith.
02
Native clients first
Android and iOS provide the primary user experience; the web interface supports the same product experience.
03
Security in the path
Auth, transport and data handling are designed into the services — not bolted on later.
04
Observable operations
Metrics and logs are part of the delivery so incidents stay diagnosable.
05
One product, many surfaces
Feed, messaging and notifications share identity and delivery conventions.
What we built
What we delivered.
Backend services
Go services covering feed, posts, messaging, notifications, search and supporting domains.
Data & cache
Persistent storage with caching where latency and fan-out demand it.
Android client
Native Kotlin client for the core social experience.
iOS client
Native Swift client aligned with the same product capabilities.
Web surface
TypeScript web experience and tooling alongside the mobile apps.
Security & operations
Hardened service paths with observability for production operations.
Architecture
System at a glance.
Several Go backend services behind native Android and iOS clients, with a TypeScript web surface. Shared identity and notification pipelines keep the product consistent across channels.
Operations favour explicit service boundaries and measurable system health — so the platform remains operational as new features are added.

Status
What we learned
What we take forward.
- 01
Social features look independent until notifications and identity force shared contracts — design those early.
- 02
Native clients reveal rough edges in an API faster than any web prototype; use the mobile experience as the benchmark for how the product feels.
- 03
Observability is part of the feature set: without it, a multi-service social stack becomes guesswork.
Next steps
What’s next.
- Deeper analytics for engagement quality — not only volume.
- Continued hardening of messaging and notification reliability.
- Selective expansion of web parity where it serves operators and users.
