Advanced Retail Automation Bot Developer Required

Looking for an experienced developer to build a high-speed, fully automated retail checkout bot for Australian retailers. The bot needs to support Kmart, Target, Big W, JB Hi-Fi, EB Games and Myer.

Requirements

include multiple checkout profiles, simultaneous product monitoring, instant add-to-cart, pre-carting where supported, one-click operation, automatic delivery selection, saved payment details and complete checkout automation. It must be capable of handling high-demand product releases, including Cloudflare verification, waiting rooms, queues, anti-bot challenges, session management and rate limiting within authorised testing arrangements. A major requirement is intelligent error recovery. If adding to cart, delivery selection or payment fails, the bot should identify the actual transaction state and continue without unnecessarily restarting the entire process. Looking for someone experienced with HTTP/GraphQL APIs, browser automation, concurrent tasks and low-latency checkout systems. Please provide your experience, estimated timeframe and quote.
