Full-Stack Node.js Developer for E-commerce Repricer and API Fulfillment Bot

I am seeking an experienced Node.js developer to build a custom backend automation tool for an e-commerce marketplace. The system will handle two core automation components: dynamic price tracking and automated order fulfillment. Core Responsibilities: 1. Automated Repricer Engine: - Programmatically scan/parse public item catalog listings to track market price shifts. - Dynamically adjust my store's pricing based on target competitor rules (e.g., matching or undercutting). - Enforce a strict "floor price" matrix to ensure the system never updates a listing below cost. 2. Webhook Order Processing & API Fulfillment: - Securely connect to the store's REST API using Client Credentials. - Process incoming order webhooks and instantly push status updates and chat confirmations. - Interface directly with a third-party gaming platform API (specifically utilizing Roblox libraries like [login to view URL] or custom HTTP requests) to programmatically trigger in-game asset delivery to the buyer. Requirements: - Advanced Node.js (Asynchronous patterns, Axios/Fetch) - Deep understanding of REST API integration and Webhook processing - Practical experience with Roblox automation/API libraries ([login to view URL] / account session management) - Strong emphasis on security (using environment variables for keys/tokens)
