FAQ
Can you work on an existing React or Next.js application?
Yes. I can work with an existing React or Next.js codebase to fix bugs, add features, refactor code, improve performance, or make other technical improvements. Please share some details about the application and what you need changed before placing an order.
Can you build a new application from scratch?
Yes. I can build React and Next.js applications from scratch based on your requirements, designs, wireframes, or an existing reference. For larger or more complex applications, please message me first so we can define the scope and choose the appropriate package.
Do you provide backend/API development?
Yes. I can build or integrate REST APIs and work on the backend required for your application, including Node.js/Express.js services, authentication, databases, and third-party API integrations.
Can you integrate third-party services or APIs?
Yes. I can integrate third-party APIs and services such as payment providers, authentication services, maps, data services, AI APIs, and other external systems. Please share the service you need integrated so I can confirm the requirements.
Can you fix bugs in my React or Next.js application?
Yes. I can investigate and fix bugs in existing React and Next.js applications, including UI issues, API problems, unexpected behavior, and performance-related issues. Please provide a description of the problem and, if possible, relevant screenshots, error messages, or access to the project.
Do you work with Figma or existing designs?
Yes. I can convert Figma designs, wireframes, screenshots, or other visual references into responsive React/Next.js interfaces. I focus on implementing the design accurately rather than providing UI/UX design services.
Can you work with APIs, databases, authentication, and dashboards?
Yes. Depending on the project, I can work with APIs, databases, authentication systems, dashboards, data-driven interfaces, and other application functionality. The exact scope depends on the complexity of the project, so please message me with your requirements before ordering larger applications.
What do you need from me before starting?
Please provide your requirements, designs or references, and relevant project details. For existing apps, include the codebase/repository and API documentation if applicable.
