### Senior Software Engineer Assessment #### 1. Code Quality & Patterns * The architecture successfully integrates Redux Toolkit and React Query, creating a robust, modern pattern for managing local and server state. * API integration uses clean Axios promise chains, but the error handling in `AssignAstrologer.ts` is brittle, returning raw errors instead of standardized failure objects. * Type safety is significantly undermined; critical domain interfaces like `AssignedAstrologerType` overuse the `any` keyword for many astrologer attributes. * The `CallUtils` WebRTC logic contains nonsensical type checks and references debugging information pointing to incorrect file paths. #### 2. Language-Specific Observations * TypeScript usage is formal but shallow, achieving structure via interfaces while failing to leverage strong typing for key fields like experience or specific categorical IDs. * The project correctly bootstraps global providers (Redux and React Query) in `App.tsx`, demonstrating professional use of the modern React ecosystem libraries. * Implementation of real-time calling features via `react-native-webrtc` suggests a complex, high-interaction requirement for astrologer consultations. #### 3. Code Structure * The repository exhibits logical separation of concerns with dedicated directories for `api`, `router`, and `utils`, promoting high maintainability (MI 81.51). * The router configuration shown in `ConsultAstrologerScreen.tsx` utilizes a structured, named export pattern, which is conducive to advanced type-safe navigation systems. * Configuration files like `google-services.json` are appropriately placed within the platform structure (`android/app`), standard for React Native projects. #### 4. Specific Improvements * **CRITICAL:** Firebase API keys and secrets are directly exposed in `google-services.json`, demanding immediate environment variable injection. * Refactor `AssignAstrologerType` to eliminate all instances of `any`, enforcing strict typing on complex astrologer domain data structures. * Standardize API error handling across the application to consistently throw exceptions, instead of masking failures via type casting (`as Promise<...>`). * In `CallUtils`, remove the redundant `typeof localMediaStream !== 'boolean'` check and ensure debug logs are production-ready. * Given the high security risk, implement a comprehensive secrets management system to secure configuration files outside the version control system.
