Scalable & Secure Backend Development with Node.js/NestJS/MySQLM J
I specialize in building scalable, secure, and high-performance backend systems using Node.js and NestJS. Whether it’s a REST API, microservices, or real-time system, I deliver production-grade code with clean architecture, optimized database design, and best DevOps practices.
What's included
Modular, Scalable Codebase
Backend developed using clean architecture principles with NestJS, organized for easy maintenance and extensibility.
REST or GraphQL API Endpoints
Well-structured endpoints following REST or GraphQL conventions, fully documented and ready for frontend integration.
Secure Authentication System
JWT, OAuth2, or API key-based login and role-based access control tailored to your app’s security needs.
Database Schema Design & Integration
Optimized schema design for MongoDB or PostgreSQL, including indexing, relations, and data validation.
Third-party Integrations
Connection with external services like Stripe, SendGrid, Firebase, or custom internal APIs.
Real-Time Features
WebSocket or event-driven architecture for real-time notifications, messaging, or tracking modules.
Deployment-Ready Backend
Ready for deployment on AWS, GCP, Azure, or Dockerized with production config, environment variables, and logging.
API Documentation
Auto-generated Swagger or Postman docs for your team or public use—easy to read, test, and share.
Testing Suite
Unit and integration tests using Jest or Supertest to ensure backend reliability and CI compatibility.
Developer Documentation
Guides for setup, running, and deploying the backend. Includes architecture overview and environment setup.
FAQs
I can develop systems for SaaS apps, marketplaces, real-time tools, dashboards, CRMs, and more.
Yes, I can build APIs tailored to your frontend stack—React, Vue, Angular, or mobile apps using React Native or Flutter.
Yes, you’ll get Swagger/OpenAPI or Postman documentation along with a README guide for running and maintaining the backend.
Absolutely. My code is modular, testable, and built with industry best practices—ready to scale and deploy.
Yes. I can break your backend into smaller services with individual deployments and shared communication layers.
Depends on your use case. I’ll guide you on the best choice based on relational needs, scalability, and flexibility.
Yes, I offer full setup for AWS, GCP, Azure, Docker, or even CI/CD pipelines with GitHub Actions or GitLab CI.
Yes, I use Jest and Supertest to write automated tests for critical backend flows and endpoints.
Of course! I offer ongoing support, bug fixes, and new feature development as part of retainer or hourly packages.
Yes. I’ve integrated Stripe, PayPal, and have built real-time features using WebSockets and Redis-based pub/sub.
