FAQ
Will you provide Swagger/OpenAPI documentation?
Yes, I include Swagger documentation in my Standard and Premium packages so you can easily test and integrate the endpoints.
Can you integrate 3rd party services like Stripe or Firebase?
Absolutely! I specialize in API integration, including payment gateways, social logins, and cloud storage services.
Is the backend ready for high traffic?
Yes, I optimize Node.js using asynchronous patterns and caching techniques to ensure it stays fast under heavy load.
Which Node.js frameworks do you use?
I primarily use Express.js for its speed and flexibility. However, depending on the project requirements, I can also work with NestJS if you need a more structured, enterprise-level architecture, or Fastify for ultra-high performance requirements.
Do you provide API documentation for the frontend team?
Absolutely. I integrate Swagger (OpenAPI) by default in my Standard and Premium packages. This allows your frontend or mobile developers to visualize and test the API endpoints interactively, ensuring a smooth integration process.
How do you ensure the security of the APIs?
Security is my top priority. I implement multiple layers of protection, including: JWT (JSON Web Tokens) for secure authentication. Helmet.js to secure Express apps by setting various HTTP headers. Input Validation using libraries like Joi or Zod to prevent malicious data.
Can you connect the backend to multiple databases?
Yes, I can design systems that interact with multiple databases if needed. Whether it’s a combination of MongoDB (for flexible data) and PostgreSQL/MySQL (for relational data), or integrating with Redis for caching, I can handle complex data architectures.
Will my API be scalable for future growth?
Yes. I follow a Modular Architecture and clean code principles. This means your backend is built to be "pluggable," allowing you to add new features or scale the system as your user base grows without needing a complete rewrite.
