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
Domain logic structured to support web, mobile, admin, and public API from a single source of truth
TypeScript and tRPC eliminate entire classes of runtime errors across the full stack
AWS deployment via SST with CI pipelines and automated quality checks from the first commit
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.
