Real-Time GraphQL API Platform

Built a high-performance GraphQL API platform serving complex data relationships with real-time subscriptions and comprehensive usage analytics for enterprise clients.

The Challenge

Enterprise clients needed to query deeply related data without the over-fetching and endpoint sprawl of REST, and they needed changes pushed to them in real time, not polled.

What We Built

We designed a type-safe GraphQL schema over the domain, served through Apollo Server with real-time subscriptions over WebSockets. Redis caching keeps hot queries fast, role-based access control governs who sees what, and rate limiting with usage analytics protects the platform while giving clients visibility into their consumption.
