I will develop wix velo custom code backend functions API setup wix website development


About this gig
Is your Wix website doing most of what you need, but falling short when your business requires custom functionality?
I specialize in building tailored Wix Velo solutions for requirements that standard Wix features cannot handle effectively. Whether you need custom backend logic, database functionality, API connectivity, dynamic pages, custom forms, calculations, filtering, or workflow automation, Ill build around your specific requirements rather than forcing your business into a generic setup.
Poorly structured custom code can create bugs, slow development, security concerns, and expensive rework.
What I can help with:
- Wix Velo custom development
- Backend functions and server-side logic
- REST/API integrations
- Wix CMS and database functionality
- Custom search and filtering
- Dynamic pages and user-specific functionality
- Custom forms and calculations
- Debugging and existing Velo code fixes
- Webhooks and external service connections
Ready to remove the Wix limitations holding your website back?
Send me your requirements, existing Velo code, or API documentation. Ill review the technical needs and recommend the right implementation before development begins.

FAQ
What can you build with Wix Velo?
I can build custom functionality such as backend functions, database logic, custom forms, calculations, search and filtering, dynamic functionality, API connections, webhooks, and other JavaScript-based Wix functionality
Can you work with my existing Velo code?
Yes. I can review existing Velo code, identify errors or structural problems, and modify or extend it where practical. For larger projects, I’ll assess the existing implementation before recommending changes
Can you integrate an external API with Wix?
Yes, provided the external service offers an accessible API and the required authentication and permissions are available. I can connect Wix functionality to appropriate external services and handle the required data flow
Can you build backend functions?
Yes. Backend functionality can be developed for server-side processing, database operations, API communication, business logic, and other requirements that should not be handled entirely in the browser
What do you need from me to start?
Usually, I need access to the relevant Wix project, a clear description of the desired functionality, any existing code, database structure, API documentation, and required credentials or permissions where applicable
Can you build custom search or filtering?
Yes. I can create custom search and filtering logic connected to Wix CMS/database content, depending on the required fields, relationships, and user experience
