Tourist AI application (backend) — GPT + geolocation + TTS

Budget: 24000 UAH Deadline: 7 days

I am interested in your project - I have relevant experience with all the key technologies you mentioned:
✅ FastAPI + OpenAI GPT — I have written many backends with AI integrations.
✅ Microsoft Azure TTS — I even wrote fast real-time plugins for voice chatbots.
✅ Experience with Google Maps API, reverse geocoding.
✅ Hosting — I can deploy the backend on a server or in a Docker container, and set up CI/CD if needed.

Estimated timelines: 4–7 days (depends on the type of hosting, file system [s3 takes longer], acceptable response delay on Flutter)

Testing and support — free for 1 month after delivery.

Budget: 23000 UAH Deadline: 15 days

Good afternoon. I am ready to complete the task.
I have extensive experience in developing mobile applications.
I mainly code in Python and hold 2nd place on the platform.

I will implement the backend for the Flutter application. I will integrate AI. I will set up the logic for receiving photos/GPS coordinates. I will implement the identification of landmarks, generate descriptions, and create audio. If necessary, I will implement any functionality. I will optimize.
I will conduct testing and provide documentation.

Feel free to write, we can discuss the details and I will start working.

Hello! I am interested in your project.
I will write a REST API using NestJS + TS + PostgreSQL.
As for AI, we can use GPT-4o mini, which is inexpensive, works quickly, and accepts images as input.
Estimated time: 6-7 days + a couple of days for risk management. However, I would like to see the complete technical specification for an accurate assessment.
