Hire Express Developer

Our Express.js developers implement modular routing, middleware architecture, and efficient error handling. We've built APIs serving 200K+ requests per minute with sub-50ms response times using Express optimization techniques including connection pooling and response caching.

We implement comprehensive security middleware including helmet for HTTP headers, rate limiting, CORS configuration, and input validation. Our security stack prevents common vulnerabilities and includes authentication middleware, request sanitization, and proper error handling.

We use clustering with PM2, implement efficient routing patterns, optimize middleware chains, and use compression. Our performance optimizations include database connection pooling, caching strategies, and load balancing that handle 100K+ concurrent requests.

We implement centralized error handling middleware, structured logging with Winston, and proper HTTP status codes. Our error management includes custom error classes, async error catching, and comprehensive monitoring that provides actionable insights for debugging.

We use Supertest for API testing, implement comprehensive unit tests with Jest, and create integration tests for middleware. Our testing strategies include endpoint testing, middleware testing, and error scenario validation with 95%+ code coverage.

We containerize Express applications with Docker, implement CI/CD pipelines, and use blue-green deployments. Our DevOps practices include automated testing, environment management, health checks, and monitoring that ensures 99.9% uptime.

We implement JWT authentication, session stores with Redis, OAuth integration, and role-based access control. Our authentication systems support multi-tenant applications, secure session handling, and integration with enterprise identity providers and SSO solutions.
