Draco Li, an engineer at Loose Button, built Triggio to automate alerts and increase productivity by creating an alert notification system that can be triggered through a simple API. The application uses Twilio SMS to send notifications, allowing users to stay up-to-date on business without losing focus on their tasks. Triggio can be used for various purposes beyond sales data updates, such as Github activity or payment notifications. Draco's self-taught programming skills and secret projects helped him develop the application to improve workplace productivity.
