FAQ
What technologies will you use?
I primarily use Next.js, React and TypeScript for the frontend, NestJS and Node.js for the backend, and PostgreSQL with Prisma for the database.
Can you build both the frontend and backend?
Yes. This gig covers full-stack development, including the user interface, backend REST API, database integration and frontend/backend communication.
Can you add authentication and user roles?
Yes. I can implement JWT authentication with access and refresh tokens, protected routes and role-based access control depending on your package and requirements.
Can you work on an existing application?
Yes. I can add new functionality, extend an existing React, Next.js or NestJS application, integrate APIs and improve existing code.
Can you build an MVP or SaaS application?
Yes. I can develop small MVPs and SaaS functionality. Larger applications should be discussed before ordering so I can review the scope and provide a custom offer.
Do I need to contact you before ordering?
For small and clearly defined tasks, you can order the appropriate package directly. For custom features, complex applications or larger MVPs, please message me first so we can confirm the scope, price and delivery time.
