Feather: A Production-Grade Social Platform Built for Extensibility

An internally built social platform demonstrating how scalable, production-ready architecture should be done — clean domain boundaries, type-safe APIs, and a foundation built to grow.

Outcomes

1 codebase
Multi-Client Architecture

Domain logic structured to support web, mobile, admin, and public API from a single source of truth

100%
End-to-End Type Safety

TypeScript and tRPC eliminate entire classes of runtime errors across the full stack

Cloud-native
Production Infrastructure

AWS deployment via SST with CI pipelines and automated quality checks from the first commit

Extensible
Built to Grow

Phase 2 roadmap includes admin dashboard, public API, mobile clients, real-time updates, and search

The Challenge

Most portfolio projects demonstrate that you can build features. Feather was built to demonstrate something harder: that you can make the right architectural decisions before the system grows, so that it doesn't break when it does. The goal was to build a real social platform — not a tutorial project — with the kind of intentional structure that supports multiple clients, future products, and long-term maintainability without a rewrite.

Our Solution

Feather is a type-safe, domain-oriented social platform built as a clean monolith with clear separation between business logic, API layer, UI, and infrastructure. Domain logic lives in isolated packages, consumed by a Next.js web app via tRPC — meaning the same core can power a future admin dashboard, mobile client, or public API without duplication. The platform ships with cursor-based pagination, optimistic UI updates, follow and feed mechanics, and a full authentication system. Infrastructure is cloud-native on AWS via SST, with CI pipelines, pre-commit hooks, and strict environment validation baked in from day one.
