Budget: 500 USD Deadline: 1 day

Good afternoon,

Interesting project, I would be happy to help with its implementation. The approximate budget will be: $4000-$6000.
To provide a more accurate estimate, some clarifications need to be discussed.
For example, here are a few questions that will significantly influence:
1. Can you provide access to the current logging system and error logs? This will help to localize the problem faster.
2. What are the current response time requirements for each stage of processing (from audio input to audio output)?
3. Is integration with other services or APIs required, besides the mentioned ones (Twilio, WebSocket, OpenAI)?

These clarifications will help assess the complexity of the work and determine additional resource needs for the successful implementation of the project.

Good afternoon,

I would like to offer my services for diagnosing and fixing issues in your voice assistant project. Experience with WebSocket, as well as various aspects of audio data processing and transmission, allows me to effectively identify and resolve such problems. I will carefully study the code you provide and determine at which specific stage the failure occurs in the audio call processing system, as well as optimize the interaction of system components for reliable operation.

My rate is $16 per hour. I can start analyzing and fixing the issues soon.

Best regards,
Maxim

Hello, Andrew,

I am Georgios Toutoudakis, a backend developer with practical experience in Twilio streaming, WebSocket servers, STT (Whisper), and TTS/GPT pipelines — exactly the stack your system uses.

Relevant experience:
Creating a real-time voice bot using Twilio + WebSocket, converting μ-law to PCM for Whisper STT

Integrated OpenAI Whisper (streaming + fallback) and troubleshooting fragment synchronization, VAD, and PCM encoding

Debugging audio stream pipelines for AI assistants (incoming sound → VAD → STT → GPT → TTS → Twilio)

Good day!

I am a Python developer with experience in creating Telegram bots, working with APIs, WebSocket, OpenAI GPT, and audio processing through Whisper. I am also familiar with Twilio and streaming services.

I am ready to analyze your current code and help you find and fix the reason why the chain "audio → STT GPT → TTS → Twilio" is not working. I can debug flows, decode audio, test VAD, set up logging and diagnostics.

I can provide a brief report indicating exactly where the problem occurs and suggest a solution.

I work until a fully functional result is achieved.

Good afternoon. I have been engaged in web programming in Python/JS/TS for over 4 years. I develop API interfaces on FastAPI/Nest.js, web platforms on Next.js/Django. Feel free to contact me, and we can discuss your task in more detail.

I have worked with Twilio many times and believe I can help with your task.
