Overview

This repository showcases an enterprise-grade frontend architecture built with React and TypeScript, inspired by patterns commonly used in large-scale platforms such as Mercado Libre.

The focus is not on visual complexity, but on scalability, performance, maintainability, and developer experience, reflecting real-world constraints found in high-traffic, multi-team environments.

This project is designed as a technical verification artifact, not a tutorial or demo.

---

Architectural Principles

• Domain-driven frontend structure
• Strong separation of concerns
• Predictable data flow
• Performance-first mindset
• Testability by design
• Team scalability over individual speed

---

Architecture Overview

This structure mirrors how frontend teams operate at scale, where multiple squads work independently on well-defined domains.

Technology Stack

• React + TypeScript
• Modern Hooks-based architecture
• Code splitting & lazy loading
• Testing: Unit + E2E
• Performance optimizations aligned with real production scenarios

Performance Strategy

• Route-based lazy loading
• Memoization of critical components
• Controlled re-renders
• Bundle size awareness
• Clear ownership of performance-sensitive code paths

Testing Strategy

• Unit tests focused on business logic
• E2E tests covering user-critical flows
• Test isolation to support CI pipelines
• Designed to scale with team size

Real-world Inspiration

This architecture is inspired by practices observed in:

• Large e-commerce platforms
• Multi-team frontend organizations
• High-traffic consumer-facing products

Patterns and decisions are aligned with environments such as Mercado Libre, where performance, accessibility, and reliability are first-class concerns.

Trade-offs & Decisions

• Prioritizes long-term maintainability over short-term delivery speed
• Introduces more structure than a typical small frontend project
• Slightly higher upfront complexity to enable multi-team scalability

Why this repository exists

• Demonstrate senior-level frontend architecture
• Show decision-making beyond code syntax
• Reflect how real teams work in production
• Serve as a reference for enterprise frontend design

Package Strategy

This repository is designed to be compatible with internal package distribution strategies (GitHub Packages / private registries).

While no public package is published, the structure supports:

• Shared UI libraries
• Internal design systems
• Versioned frontend modules
