WordPress AI Platform Development

I already have a live WordPress website: https://bhoomiindiaai.com

I do NOT want a new website.

I need an experienced WordPress developer to work on my existing website and create a custom AI platform.

Requirements:
- AI Chat (ChatGPT style)
- AI Image Generator
- AI Writing Assistant
- AI Photo Editor
- AI File Upload & Analysis
- User Login & Registration
- User Dashboard
- Chat History
- AI Image History
- Responsive Mobile Design
- Fast and Secure
- Admin Panel
- API integration (OpenAI or Google Gemini)

Important:
- Build everything on my existing WordPress website.
- Do not create a new website.
- My domain, hosting, WordPress admin, database, and source code must remain under my ownership.
- Deliver complete source code after the project is completed.
