I’m building a real-time AI voice agent that runs on both my web app and a desktop client, and I need a full-stack developer who can own the entire integration flow in Python/Django. The agent must handle, in real time: • Voice recognition • Natural language processing • Speech synthesis You’ll wire these capabilities into the existing Django back-end, expose clean REST and WebSocket endpoints for the front-end, and make sure the same logic is accessible from a lightweight desktop wrapper (Electron or similar—open to suggestions). Payment processing is the final piece. Once a call is completed the system should automatically trigger billing, so experience with common gateways (Stripe, PayPal, etc.) and secure token handling is essential. Deliverables will include a working web interface, a packaged desktop client, all server-side code, and clear setup documentation so I can deploy and scale independently. If you’ve shipped voice products before and are confident tuning latency down to conversational levels, I’m ready to get started right away.

Hello, I’m a full-stack developer with strong expertise in Python/Django, WebSockets, and real-time AI integrations, and I can help you build your real-time AI voice agent across web and desktop. I understand the critical requirement here is not just accuracy but latency reduction to conversational levels, and I’ve worked on systems involving speech recognition, NLP, and synthesis pipelines optimized for real-time interaction. Here’s how I’d approach your project: Voice Recognition: Integration with low-latency APIs or custom ASR (Whisper/DeepSpeech) for real-time transcription. NLP Layer: Plug-in to your AI logic for intent recognition and dynamic response handling. Speech Synthesis: Real-time TTS for natural replies (edge-optimized to minimize lag). Django Backend: REST + WebSocket endpoints for synchronous & streaming events, secured with token auth. Frontend: Web app integration and a lightweight Electron desktop wrapper for cross-platform access. Payments: Automatic billing post-call via Stripe/PayPal, with secure tokenization and compliance. Scalability: Modular architecture with caching, load balancing, and deployment docs for independent scaling. I will deliver a fully working web interface, packaged desktop client, server-side code, and complete deployment guide. Post-launch support for scaling and latency tuning can also be provided.
