FAQ
Q: Do you use Node.js and Express.js for API development?
A: Yes! I build high-performance, secure, and scalable REST APIs using Node.js and Express.js. This powerful stack allows me to handle complex backend routing, middleware implementation, database communication, and user authentication flawlessly.
Q: Which databases do you use for backend API development?
A: I primarily work with MongoDB (NoSQL) and PostgreSQL (Relational Database), depending on your project requirements, ensuring structured, optimized schemas and secure data handling.
Do you work with both Frontend and Backend API integration?
A: Yes! I can build a custom Node.js/Express.js backend from scratch, or I can seamlessly integrate existing REST APIs into your frontend using tools like Axios or the Fetch API in React.js and Next.js.
Q: Can you integrate third-party APIs like Stripe, PayPal, or Google maps?
A: Absolutely. I specialize in connecting frontend applications to external web services, including payment gateways (Stripe, PayPal), authentication tools (Firebase, Auth0), and custom SaaS dashboards.
Q: How do you ensure the security of the APIs?
A: I implement bulletproof security measures, including JSON Web Tokens (JWT) for user sessions, Firebase Authentication, secure password hashing, environment variable protection, and strict role-based access control.
Q: What do you need from me to start working on the project?
A: Please provide your clear project requirements, existing source code (if any), API documentation (for third-party integrations), and any specific UI/UX designs or wireframes you want me to use.
