API & Backend Development
REST. GraphQL. WebSockets. Built for reliability, speed, and developer experience.
Production-grade REST and GraphQL API development. Node.js, NestJS, Express, Python backends. Microservices, real-time WebSocket systems, and third-party integrations. Enterprise-scale architecture.
The real challenge
A bad API architecture costs you 10x more to fix later than to build right the first time. Versioning, authentication, rate limiting, error handling, documentation — these aren't optional for enterprise clients.
