My name is Ivan, I am a freelance developer with over 3 years of experience working with AI integrations. Recently, I have worked on several projects where I combined Twilio Voice/WhatsApp, OpenAI Whisper, and GPT-4 to automate call and chat message processing.
Briefly about my experience:
Set up webhooks for Twilio Voice and WhatsApp to receive audio and text
Integrated Whisper API for fast and accurate transcription of conversations
…
Used GPT-4 to generate contextual responses in real-time
Logged results (transcripts, responses, metadata) into Google Sheets and set up dashboards in Looker Studio
Integrated data transfer from CRM via REST API or through Make/Zapier
How I approach this MVP:
Twilio Voice & WhatsApp
– Register and test webhooks, verify audio format, handle calls and chats.
Whisper API
– Configure audio transmission from Twilio, optimize recognition for low latency.
GPT-4
– Create prompts with conversation context, system messages to maintain the desired tone.
Google Sheets & Looker Studio
– Automate data entry into sheets, set up clear dashboards for analytics.
Optional: CRM
– Transfer key conversation data to your CRM via API or Make/Zapier.
I am ready to provide examples of specific code snippets or technical details upon first request. I would be happy to discuss stages, budget, and timelines.
Best regards,
Ivan

We can create an MVP of a voice and WhatsApp assistant for you.
About us-
We:
• Have done many similar AI/chatbot integrations;
• Are familiar with Twilio, OpenAI API, Google Sheets API, and many others;
• Constantly work with REST API;
• Understand well what MVP means, and will offer you the optimal technical solution.
… We would suggest building the backend on n8n, deploying it on a cloud server, and the managing frontend on some constructor, like Bubble. Simple and without design. It could replace Looker and help manage the system more easily.
Such a system will be easy to expand if needed, and easy to maintain.
We are ready not only to build the system for you but also to provide its ongoing maintenance.
We will offer you good conditions. Contact us.

I am creating tools like https://bedtimestory.ai and https://doubtbuddy.com, where many parts need to work together seamlessly.
For your assistant, I would first create a quiet space where we can safely test calls and messages. This helps us listen to how it feels before anything is launched. I think it’s important how the assistant sounds and when it speaks, not just what it says.
I have one idea — to allow you to listen to certain voice moments via a private link so you can improve things without touching the settings.
If you like this, I want to work on it carefully and build it in parts.

I have already created several tools that connect speech, AI, and messages. I enjoy working on systems that feel smooth and human-like, especially when voice and text are combined. For this, I would start by setting up Twilio Voice and WhatsApp in a way that allows easy testing without the need for real calls at each stage. Then I would integrate Whisper to get voice input, clean it up a bit, and pass it to GPT for generating a natural response.
I usually wrap everything in FastAPI because it simplifies work and allows me to quickly add automation or make changes later without disrupting other parts. Integration of Google Sheets and CRM can be done in parallel, so all data moves in the background without delay. I would also suggest adding a soft registration system that tracks each conversation without making it heavy or slow. This will help later when you connect it to Looker or review messages for improvements.
