You will get secure REST APIs with Node.js, NestJS & PostgreSQL
Project details
Need a backend developer to build secure, scalable REST APIs?
I develop production-ready backend systems using Node.js, NestJS, PostgreSQL, Prisma ORM, and TypeScript. Whether you're building a new application or improving an existing backend, I focus on clean architecture, secure authentication, high performance, and maintainable code.
I can build REST APIs, authentication systems, role-based access control (RBAC), database design, third-party API integrations, payment integrations, and real-time backend features. Every project is developed with scalability, security, and long-term maintainability in mind.
You'll receive clean source code, well-structured APIs, database design, proper error handling, API documentation when required, and reliable communication throughout the project.
Please contact me before placing an order so we can discuss your requirements and select the best package.
