Software architecture
Software architecture is the high-level design of a software system, encompassing its structure, behaviour, and key technical decisions. A skilled software architect creates the blueprint for robust, scalable, and maintainable software, ensuring it aligns with business objectives and technical constraints. They bridge the gap between business requirements and technical implementation, making crucial decisions that impact the project's long-term success.
