Full Backend Application DevelopmentKelechi Nwaji
I specialize in building robust, scalable, and secure backend applications from the ground up. Whether you need a well-structured API, real-time features, database optimization, or seamless authentication, I ensure your backend is efficient, maintainable, and future-proof. With expertise in NestJS, Node.js, PostgreSQL, Redis, and cloud deployment, I deliver high-performance solutions tailored to your business needs. 🚀
What's included
Backend Architecture Design
- A well-structured architecture blueprint for the application.
- Selection of monolithic or microservices-based architecture depending on project needs.
- API design with RESTful or GraphQL endpoints.
API Development & Documentation
- Fully developed secure and scalable APIs using NestJS & Node.js.
- Well-documented API endpoints using Swagger (OpenAPI) or
Postman collections.
- Request validation and error handling for seamless client integration
Authentication & Authorization System
- User authentication with JWT, OAuth, or session-based auth.
- Role-based access control (RBAC) for managing user permissions.
- Secure password hashing and authentication best practices.
Database Design & Optimization
- Well-structured database schema (PostgreSQL, MySQL, MongoDB).
- Indexing and query optimization for better performance.
- Database migrations and data integrity validation.
Deployment & CI/CD Integration
- Fully deployed backend on Vercel, AWS, or DigitalOcean.
- CI/CD pipelines using GitHub Actions, Jenkins, or GitLab CI.
- Dockerized environment for easy scalability.
Security Best Practices
- API rate limiting and CORS setup.
- Data encryption (sensitive data protection).
- Logging & monitoring for debugging and tracking API usage.
Post-Launch Support & Documentation
- Deployment guide and backend setup documentation.
- 1-2 weeks of post-launch support for issue resolution.
- Codebase walkthrough (if required)
FAQs
I primarily use NestJS, Node.js, PostgreSQL, MongoDB, Redis, and BullMQ to build scalable and high-performance backend applications. However, I can also use other stacks based on your project needs.
Yes! I can integrate various third-party APIs, including payment gateways (Stripe, PayPal), authentication providers (OAuth, Firebase), and cloud services (AWS, Google Cloud) to enhance your application's functionality.
I follow best security practices, including JWT authentication, OAuth, API rate limiting, data encryption, secure headers, and input validation to protect your application from vulnerabilities.
Absolutely! I include well-structured API documentation using Swagger (OpenAPI) or Postman collections, making it easy for frontend developers or third parties to integrate with the backend.
Yes, I design efficient database schemas, optimize queries, implement indexing, and set up backup strategies to ensure a fast and reliable database system.
I offer post-launch support for bug fixes and optimizations. If you need long-term maintenance, I can create a custom support plan based on your requirements.
I can deploy your backend on platforms like AWS, DigitalOcean, Heroku, Vercel, or a custom server. I also set up CI/CD pipelines to automate testing and deployment.
Yes! I build the backend with scalability in mind, making it easy to add new features without major refactoring. You can always request additional functionalities in the future.
