FAQ
What technologies do you use for backend development?
I use Node.js with NestJS framework for building structured, scalable REST APIs, along with PostgreSQL as the relational database. I also work with TypeORM or Prisma for database modeling and integration.
Do you provide API documentation for frontend integration?
Yes, I set up interactive Swagger (OpenAPI) documentation so your frontend developers (React, Flutter, iOS/Android) can easily view, test, and integrate the endpoints.
Can you handle user authentication and authorization?
Absolutely. I implement secure JSON Web Tokens (JWT), password hashing using bcrypt, and Role-Based Access Control (RBAC) to manage user permissions.
Do you help with database migration and deployment?
Yes, I can assist in setting up database migrations, containerizing the application using Docker, and deploying the backend to platforms like AWS, Render, Heroku, or DigitalOcean.
What do I need to provide before starting the project?
Please provide your API requirements, database schema details (if any), user roles, and any specific business logic or third-party services you need integrated.
