Device: - Extract monolithic functions into focused helpers - Leverage ssl_cert library functions for validation/operations - Add comprehensive documentation and fix pattern matching warnings - Organize with public API at top, internal helpers at bottom HTTP Server: - Reorganize functions by functionality with clear sections - Add module constants for hardcoded values (ports, timeouts, paths) - Eliminate duplicate code with shared utility functions - Add type specifications and comprehensive documentation - Standardize error handling and improve function naming Key benefits: - Better maintainability through focused, single-purpose functions - Increased code reuse by leveraging existing libraries - Production-ready code following Erlang best practices ---
