WhatsApp Garbage Collection Bot

Built a zero-maintenance, serverless integration that fetches daily schedules from Google Calendar and dispatches HTTP POST requests to a WhatsApp API gateway. Designed to solve a real-world neighborhood problem by fully automating routine notifications using time-driven triggers (cron).
