Things a Senior Developer Must Know

Key principles, practices, and patterns I prioritize to build stable, scalable, and secure products.

State Management & Architecture

Centralized state using Redux Toolkit, typed selectors, modular reducers, and debug tooling for predictable app state.

Secure API Handling

Centralized API wrapper, token-based authentication, automatic session management, and robust error handling.

Device & Environment Security

Checks for compromised devices, initializes device info globally, handles platform differences, and enforces security-first policies.

Global App Configuration

Singleton pattern for global variables, graceful handling of optional values, and consistent configuration for APIs and analytics.

Code Maintainability & Best Practices

Modular folder structure, reusable utilities, typed interfaces, defensive coding, and clear separation of concerns.

UX, Performance & Stability

Safe area handling, gesture support, status bar control, smooth app initialization, and OTA updates for scalable deployment.

Security-First Development

VAPT mindset, secure storage, session validation, password & input validation, and defensive API access control.

Scalable & Maintainable Project Structure

Clear folder separation, reusable constants, async initialization, and consistent responsive design for long-term maintainability.

Observability & Debugging

Centralized logging, debug flags for APIs, Reactotron integration, and structured error handling for production stability.
