Python Developer for Modular Backend Automation & API Integration

Looking for an expert Python developer to build a scalable, modular automation system. The system must follow a Modular/Plugin Architecture, consisting of a central Core Engine and a separate Data Sync Module (Target 1). In the future, we will plug additional target modules into this same engine. Key Responsibilities: Core Engine: Fetch dynamic parameters from a Google Sheet to orchestrate background tasks. Data Sync Module: Interface with a major online platform. Must have proven experience handling advanced request headers, session management, and proxies to ensure stable connections. Data Management: Implement a local database (SQLite) for deduplication to ensure records are only processed once. Alerts: Integrate with a WhatsApp gateway to send real-time structured notifications. How to Apply: 1. Start your application with the word "SYSTEM". 2. Briefly describe your experience with modular Python architecture. 3. Which WhatsApp API do you recommend for automated alerts?
