Desktop Multi-Order Execution Tool – API Integration & Real-Time Automation

We are looking for an experienced developer to build a lightweight desktop application for fast, reliable multi-order execution through a third-party trading platform’s official API. The application should allow a user to configure and save multiple orders in advance, then submit the entire order set through a single button or keyboard shortcut. The primary objective is to reduce the delay and manual effort involved in placing multiple time-sensitive orders individually. This is a focused execution tool, not a full trading platform or analytics product. Core Requirements * Simple, responsive desktop interface * Ability to create, edit, save, and load multi-order presets * One-click or hotkey-based batch submission * Direct integration with the platform’s official API * Clear status for each order, including submitted, accepted, rejected, partially filled, and filled * Protection against accidental duplicate submissions * Cancel-all functionality for outstanding orders * Secure local storage of API credentials * Reliable error handling, logging, and connection-status monitoring * Support for both test and live environments, where available The application should be optimized for speed and ease of use. The user must be able to prepare an order set beforehand and execute it immediately when needed without navigating through multiple screens. Preferred Experience * Python desktop application development * REST API and WebSocket integration * Trading, prediction-market, brokerage, or exchange APIs * Real-time order execution and status monitoring * Secure credential handling * Desktop packaging for Windows and/or macOS * Risk controls and transaction-safe application design When applying, please include: * Examples of comparable trading, automation, or real-time API tools you have built * Your recommended desktop technology and architecture * How you would handle partial fills, rejected orders, timeouts, and duplicate submissions * Your estimated timeline for an initial working version * Any relevant experience with batch-order or low-latency execution workflows Additional platform documentation and workflow details will be shared with qualified candidates.
