We are looking for an experienced Node Developer to build a robust backend system that powers our web and mobile applications. This project requires deep knowledge of backend engineering, modern JavaScript standards, API development, database integrations and performance optimization.
The ideal developer should understand how to design clean API endpoints, structure backend code for long term maintainability, handle large data flows and follow security best practices. You will work closely with our frontend and mobile teams to ensure efficient communication between the server and the client.
Your work will include building REST APIs, setting up business logic, validating requests, handling authentication, integrating third party services, tuning database queries and deploying the backend in a production ready environment. Knowledge of Express or Nest, asynchronous programming, caching strategies and error handling will be essential.
We appreciate developers who communicate clearly, think independently, write organized code and understand how to build systems that scale. If you have handled real world production apps before and can deliver stable backend solutions, this project is ideal for you.
✅ KEY RESPONSIBILITIES
Develop backend services using Node and modern JavaScript
Build REST APIs with clean routing and structured response formats
Integrate MongoDB or PostgreSQL with optimized queries
Implement authentication using JWT or OAuth
Create reusable service modules for business logic
Configure validation for all incoming requests
Integrate third party services such as payment gateways or email systems
Implement caching and performance improvements
Handle asynchronous tasks and background jobs
Write logs and structured error handling
Perform load testing and optimize bottlenecks
Prepare deployment ready versions for production
Write clear documentation for API usage
Collaborate with frontend and mobile developers
Provide weekly status reports and updates
✅ REQUIRED SKILLS
Strong experience with Node latest LTS version
Expertise in Express or Nest frameworks
Solid understanding of asynchronous JavaScript
Experience with MongoDB or PostgreSQL
Strong API design abilities
Knowledge of authentication and security practices
Ability to write modular, clean and documented code
Familiarity with Docker and container environments
Experience integrating third party APIs
Git version control knowledge
Understanding of CI and CD pipelines
Error tracking and monitoring tools familiarity
Ability to handle high traffic API structures
Good communication skills
Portfolio or links to previous backend projects
✅ TOOLS AND TECHNOLOGIES
Node latest LTS
Express or Nest
MongoDB or PostgreSQL
Mongoose or Prisma
Redis for caching
Docker
GitHub or GitLab
Postman or Insomnia
JWT authentication
PM2 or Docker Compose for deployment

✅ DETAILED TECHNICAL BREAKDOWN
Core Competencies
Your backend must be modular, scalable and secure. Code should follow a clear folder structure with controllers, services, models, middlewares and helpers separated for easy maintenance.
Technical Workflow
Define API requirements and data models
Build authentication and role based access
Set up database schemas and relationships
Develop efficient business logic modules
Optimize API responses and payload sizes
Implement caching for repeated queries
Handle rate limiting and request throttling
Deploy using Docker or cloud hosting
Best Practices
Follow clean code standards
Use environment variables for configuration
Keep controller logic thin and business logic separate
Use proper status codes and structured response formats
Log errors with enough detail for debugging
Simple Code Example
const loadUser = async id => {
try {
const user = await UserModel.findById(id)
return user
} catch (error) {
console.log("User fetch error", error)
return null
}
}
