Developed a JSON-based configuration for the pqrs-org/KE-complex_modifications repository that redefines the Caps Lock key to function as a Hyper key when held and as Backspace when tapped. This feature targeted power users seeking efficient keyboard workflows and was delivered through a configuration-driven approach that minimizes maintenance overhead. The work involved end-to-end configuration management, from design to repository integration, and emphasized maintainability by isolating changes within a single, clear JSON file. By leveraging skills in keyboard customization and JSON, the developer enabled scalable, user-friendly key remapping without requiring code changes, supporting future adaptability and streamlined configuration updates.
