AI Call Assistant Development for Dental Office

I'm seeking an experienced developer to create a custom AI call assistant tailored for my dental office. The AI will handle after-hours calls from patients and is essential for managing our scheduling and logging needs.

Key Requirements:
- Multilingual: Must fluently speak English, Spanish, and ideally Portuguese.
- After-Hours Call Handling: Respond to patient calls outside of office hours.
- Needs Assessment: Ask pertinent questions to determine patient needs (emergency, cleaning, pain, etc.).
- Scheduling: Book appointments into a private Google Calendar ("ghost schedule") without interfering with our live schedule.
- Logging: Record caller details and conversation summaries in Google Sheets.
- Integration: Must work with our existing traditional phone system, no third-party platforms or subscriptions allowed.

Ideal Skill Set:
- Proficiency in AI and natural language processing
- Experience with Google Calendar and Google Sheets integrations
- Familiarity with traditional phone systems and VoIP
- Strong programming skills to build a custom solution

I look forward to your proposals!
