FAQ
How do you ensure the security of the REST APIs?
Security is my priority. I implement industry-standard protections including JWT (JSON Web Tokens) for authentication, Bcrypt for password hashing, and Helmet.js to set secure HTTP headers. I also handle CORS configurations and protection against common threats like SQL Injection and XSS.
Which Node.js frameworks do you use?
Depending on your project's scale, I primarily use Express.js for lightweight, high-performance apps or NestJS if you require a highly structured, enterprise-grade architecture with native TypeScript support.
Can you connect the API to my web or mobile app?
Yes, I can integrate the backend API with web apps, Flutter apps, React apps, and other frontend or mobile platforms.
How do you handle API documentation?
I provide full, interactive documentation using Swagger (OpenAPI). This allows your frontend team or third-party users to test endpoints directly from a browser with clear definitions of request/response structures.
Can you integrate third-party services into my API?
Yes, I can integrate payment gateways, cloud services, external APIs, and other third-party platforms.
