Tech Stack
Our Node.js team excels at crafting fast, scalable, and secure backend solutions that power real-world applications. From APIs to microservices, we bring performance and reliability to every project.
Our Node.js developers follow strict security standards, ensuring safe, reliable, and high-performance backend systems.
We mandate the validation and sanitization of all incoming user input (body, queries, headers) to prevent injection attacks (SQL, NoSQL, XSS). We use libraries like Express-Validator to enforce accepted data schemas.
We enforce the use of Async/Await and Promises, eliminating error-prone callbacks. This maintains code clarity, ensures proper central error handling, and prevents blocking the single-threaded Node.js event loop.
We regularly audit all third-party packages using tools like npm audit and Snyk. By minimizing dependencies and actively updating to stable versions, we protect your application from known external vulnerabilities.
We use security middleware like Helmet to set crucial HTTP headers, protecting the application from common web vulnerabilities (like XSS and clickjacking). We also ensure secure, non-default session cookie names.
We implement strong authentication protocols using Bcrypt for password hashing and JWT/OAuth for session security. We also implement Rate Limiting middleware to prevent Denial of Service (DoS) and brute-force attacks on login endpoints.
We never hardcode sensitive information (API keys, credentials). All secrets are stored in secure environment variables, and the server is always run in a controlled, non-root user environment with production monitoring enabled.
We strictly enforce code practices that prevent the Node.js event loop from blocking, which is critical for maintaining asynchronous performance. Developers avoid CPU-intensive synchronous operations and use worker threads when necessary, guaranteeing the backend remains responsive under high concurrency.

CI/CD integration and deployment to the cloud (AWS/Azure). We set up monitoring to guarantee continuous, high-speed system performance.
Common hiring mistakes
Hiring Node.js developers shapes the backbone of your product. Learn how to find true backend experts, avoid hiring pitfalls, and build a team that delivers secure, scalable, and high-performance applications.
Hiring a developer who treats Node.js like a standard multi-threaded language (like Java), leading to code that blocks the single event loop. This causes the entire server to freeze under minimal load, resulting in catastrophic performance failure and downtime.
Focusing on functional code while neglecting to secure data pathways. Vetting must check for implementation of input validation and sanitization (to prevent SQL/NoSQL injection) and proper use of JWT for robust authentication across the Express server.
The developer uses synchronous code or mishandles Promises/Async-Await, causing unexpected uncaught exceptions that crash the entire application process. Proper vetting must confirm the developer can implement centralized, non-breaking error handling using try/catch and global listeners.
Hardcoding sensitive information (API keys, database credentials) directly into the repository or failing to manage packages. A reliable expert must demonstrate proficiency with environment variables (.env files) and regularly run npm audit to ensure dependency integrity.
