Build Amazing Project with
Node.js API DevelopmentExpress.js ApplicationsReal‑time ServicesMicroservices Architecture

RESTful APIs and GraphQL services with Express.js, Fastify, or NestJS. Clean architecture patterns, middleware design, input validation, error handling, and comprehensive API documentation with OpenAPI/Swagger specifications.

Seamless integration with PostgreSQL, MongoDB, MySQL, and Redis using Prisma, Mongoose, Sequelize, or TypeORM. Database migrations, connection pooling, query optimization, and transaction management for reliable data operations.

Secure JWT‑based authentication, OAuth2/OpenID Connect integration, role‑based access control (RBAC), session management, password encryption, and multi‑factor authentication for enterprise‑grade security.

WebSocket implementations with Socket.io for chat applications, live notifications, collaborative tools, and real‑time dashboards. Event‑driven architecture and pub/sub patterns for scalable real‑time features.

Distributed system design with service discovery, inter‑service communication, message queues (Redis, RabbitMQ), API gateways, and containerization with Docker for scalable, maintainable microservices.

Application profiling, memory leak detection, CPU optimization, caching strategies (Redis, Memcached), load balancing, clustering, and horizontal scaling for high‑performance applications under heavy load.

Comprehensive testing with Jest, Mocha, and Supertest for unit, integration, and API testing. Test‑driven development (TDD), code coverage analysis, and automated testing pipelines for reliable code quality.

OWASP security best practices, input sanitization, SQL injection prevention, CORS configuration, rate limiting, security headers, vulnerability scanning, and compliance with GDPR, HIPAA, and SOC 2 standards.

AWS, Azure, and Google Cloud deployment with Docker containers, Kubernetes orchestration, CI/CD pipelines, infrastructure as code (Terraform), monitoring with Prometheus/Grafana, and automated scaling.

Payment gateway integration (Stripe, PayPal), email services (SendGrid, AWS SES), cloud storage (AWS S3, Cloudinary), analytics tracking, CRM integration, and social media APIs for comprehensive functionality.

Application monitoring with Winston, Morgan, and structured logging. Error tracking with Sentry, performance monitoring, health checks, alerting systems, and comprehensive observability for production applications.

Ongoing maintenance, security updates, performance monitoring, bug fixes, feature enhancements, and 24/7 technical support with SLA agreements to ensure continuous application reliability and performance.
