Overview I am looking for a high-level [login to view URL] Automation Engineer to build a backend "Instant Deployment Engine" for an AI Voice Agent service. The goal is to automate the end-to-end provisioning of a Retell AI agent immediately following a frontend form submission. You will be responsible for connecting a custom Webhook trigger to a series of API calls (Retell AI, OpenAI) and database updates (Google Sheets), ending with a theatrical HTTP 302 redirect. The Tech Stack - Automation: [login to view URL] (Advanced Logic & Error Handling) - Voice AI: Retell AI API - Brain: OpenAI API (GPT-4o) - Database: Google Sheets - Frontend Integration: Webhook-based (302 Redirects) Key Responsibilities - Data Sanitization: Use Regex to standardize phone number inputs. - Inventory Management: Create a "Bench" system in Google Sheets to pull available phone numbers and "lock" them to a client. - Dynamic Prompt Engineering: Use OpenAI GPT-4o to generate unique system prompts based on user input. - API Orchestration: Create Retell agents and bind phone numbers via HTTP PATCH/POST requests. - Timing & UX: Ensure the entire scenario executes within a specific 10–12 second window to align with our frontend "calibration" animation. Required Skills - Expert-level knowledge of [login to view URL] (HTTP modules, Webhook responses, and advanced filters). - Experience with Retell AI API or similar Voice-over-IP AI platforms. - Proficiency in Regex and JSON formatting. - Strong understanding of Error Handling (Breaks, Retries, and Error paths). Project Deliverables I have a detailed, 9-module Statement of Work (SOW) ready to share with the right candidate. The logic is already mapped out; I need an expert to execute the build, test the latency, and ensure the 302 redirect functions perfectly. This is a 4 - 6 hour project at most. I am looking for a clean, professional build. This is the first of many automations. If you can make this run smoothly and handle the redirect logic without errors, I have a massive backlog of work for you. Please start your proposal with the word "ARIA" so I know you have read the requirements.

Hello "ARIA", I am a full stack developer with strong experience in automation and API orchestration workflows. I have done complex webhook-driven scenarios using advanced HTTP modules, filters, error handling, and controlled response timing. If latency or redirect issues occur, I will provide structured debugging and implement reliable 302 response handling within the required 10–12 second window. Experience includes integrating OpenAI APIs for dynamic prompt generation and handling structured JSON payloads. I will provide a clean Bench inventory logic in Google Sheets with proper locking mechanisms and Regex-based data sanitization. The automation will provide secure Retell AI agent provisioning with controlled POST and PATCH sequences and robust retry paths. This approach will satisfy your requirement for a professional, production-ready Instant Deployment Engine built with precision and scalability in mind. Warmest regards, Ahmed
