FAQ
What do you need from me to get started?
I’ll need clear requirements, your preferred technology stack (if any), and access to relevant resources (like database credentials, API keys, or repositories).
What technologies do you use for backend development?
I mainly work with Node.js, Express.js, and NestJS using JavaScript and TypeScript. For databases, I work with MongoDB, PostgreSQL, and MySQL, along with caching solutions like Redis.
Can you integrate third-party APIs into my project?
Yes, I can integrate payment gateways, authentication providers, cloud storage (e.g., AWS S3), and other third-party services into your backend.
Will my backend be secure?
Yes, I follow industry best practices including JWT authentication, data encryption, input validation, and rate limiting to ensure your APIs are safe and reliable.
Can you work with an existing project or only new projects?
I can do both. I can build a backend from scratch or review, debug, and optimize your existing Node.js/TypeScript code.
Do you also write tests for the backend?
Yes, I can implement unit and integration tests to make sure your backend is reliable and easy to maintain.
How do you handle communication during the project?
I ensure regular updates via Fiverr messages, and I’m open to scheduled check-ins for progress tracking.
