Python Developer: TradingView Webhook to Interactive Brokers API (ib_insync) Complex Order Routing

Project Overview: I am seeking an expert Python developer to build a lightweight, local automation script that bridges custom TradingView indicator alerts to Interactive Brokers (IBKR) for automated options execution. Core Deliverables: Webhook Listener: A local Python script that securely listens for JSON payloads sent via TradingView webhooks. Dynamic Option Chain Scanner: Upon receiving a payload containing specific parameters (Ticker, Target Delta, DTE), the script must query the live IBKR option chain (using ib_insync or ib_async), find the exact or closest available strikes matching that Delta, and calculate secondary strikes based on distance to the current spot price. Complex Multi-Leg Order Routing: The script must dynamically assemble these strikes into a specific 5-leg complex combo order (combining a credit vertical spread, two debit vertical spreads, and a naked wing) and route it to the market as a single transaction using mid-price algorithmic fills. Rigorous Error Handling & Logging: The code must include strict safeguards (rate limits, bid/ask spread checks, and fallback logic if an exact strike or delta is unavailable) to ensure no rogue orders are fired. Developer Requirements: Demonstrated expertise with the Interactive Brokers API (ib_insync framework heavily preferred) and TWS/IB Gateway. Deep understanding of options mechanics, including how to handle complex multi-leg combinations and delta sourcing. Excellent, proactive communication. Weekly availability during standard New York market hours (EST) for live testing. Must be located in the United States (required for IP protection and NDA enforcement). Workflow & Milestones: Initial development and testing will be done exclusively using an IBKR Paper Trading account. The project will be managed via two strict milestones: 1) Full execution validation in a paper environment, and 2) Live market deployment verification using a single test contract. If you have read this entire post and have experience with IBKR options routing, please start your proposal with the word "DELTA" and briefly describe a past algorithmic trading project you have built.
