juanatsap	71d9258c58	feat: add application-level data caching for CV/UI ... Eliminate per-request file I/O by loading CV and UI data once at startup. ## Problem - LoadCV() and LoadUI() were called on every request - Each call read from disk and unmarshaled JSON - 6 locations affected: cv_cmdk, cv_helpers, cv_contact ## Solution - New `internal/cache` package with language-keyed cache - Data loaded once at startup via `cache.New(["en", "es"])` - Handlers use `h.dataCache.GetCV(lang)` / `GetUI(lang)` - Thread-safe concurrent reads via sync.RWMutex - Deep copy for mutable slices (Experience, Projects) ## Performance - Before: ~3ms file I/O per request - After: <1µs cache lookup (~3000x improvement) ## Files - internal/cache/data_cache.go (new) - internal/cache/data_cache_test.go (new) - internal/cache/README.md (new) - internal/handlers/cv.go (added dataCache field) - internal/handlers/cv_*.go (use cache) - main.go (initialize cache at startup)	2025-12-06 15:57:23 +00:00
juanatsap	f3842a3486	fix: connect EmailService to contact form handler ... The contact form was logging submissions but never actually sending emails. This commit: - Adds EmailService field to CVHandler - Initializes EmailService in main.go with SMTP config - Calls SendContactForm in HandleContact handler - Updates all test files to pass nil for emailService parameter	2025-12-02 14:27:03 +00:00
juanatsap	4528e04bad	feat: Complete all remaining Future Improvements (#4-8) ... Implemented 5 additional architectural improvements: 1. Response Types (types.go) - APIResponse with Success, Data, Error, Meta fields - ErrorInfo with Code, Message, Field, Details - MetaInfo with Timestamp, Version, RequestID - SuccessResponse() and NewErrorResponse() helpers - HealthCheckResponse for health endpoint - Consistent JSON API responses 2. Validation Tags (types.go) - Added struct tags to LanguageRequest - Added struct tags to PDFExportRequest - Declarative validation rules (oneof, required) - Self-documenting validation constraints - Ready for go-playground/validator integration 3. Context Helper Functions (middleware/preferences.go) - GetLanguage(), GetCVLength(), GetCVIcons(), GetCVTheme(), GetColorTheme() - IsLongCV(), IsShortCV() boolean helpers - ShowIcons(), HideIcons() boolean helpers - IsCleanTheme(), IsDefaultTheme() boolean helpers - IsDarkMode(), IsLightMode() boolean helpers - 13 new convenience functions for cleaner code 4. Typed Errors (errors.go) - ErrorCode constants for all error types - DomainError with Code, Message, Err, StatusCode, Field - Unwrap() support for error chains - WithError() and WithField() fluent builders - InvalidLanguageError(), InvalidLengthError(), etc. - PDFGenerationError(), MethodNotAllowedError(), RateLimitError() - 13 error codes, domain-specific constructors 5. Benchmark Tests - handlers/benchmarks_test.go (11 benchmarks) - middleware/benchmarks_test.go (12 benchmarks) - Sequential benchmarks for handlers, middleware, request parsing - Parallel benchmarks for concurrent load testing - Response creation benchmarks - Helper function benchmarks Benefits: - Type Safety: Validation tags and structured types - Developer Experience: 13 context helpers reduce boilerplate - Error Handling: Domain-specific errors with codes - Performance Monitoring: 23 benchmarks for regression detection - API Consistency: Standardized response formats - Maintainability: Self-documenting validation and errors Testing: - All unit tests pass - All benchmarks working - Build succeeds - No breaking changes	2025-11-20 18:05:45 +00:00
