👉 Extras engineering refers to the additional layers or components that are integrated into a system beyond its core functionality, often to enhance performance, add new capabilities, or improve user experience. These can include advanced algorithms for better decision-making, machine learning models for predictive analytics, user interface enhancements for intuitive interaction, security protocols to protect data, and scalability solutions to handle increased loads. Essentially, extras engineering aims to enrich the base system, making it more robust, versatile, and capable of meeting complex demands in various applications, such as IoT devices, cloud services, or sophisticated software platforms.
