⚡ Engineering Highlights: Why This Exists

Most frontend tutorials cover the "happy path" — what happens when everything goes right. This repository exists to document the rest. My goal is to bridge the gap between feature implementation and systems engineering.

The core of this project is a collection of architectural case studies presented in a Problem/Solution format:

🧩 The Problem: Real-World Edge Cases

Instead of generic "how to" guides, every article begins with a difficult constraint found in production environments. I tackle the specific, messy details that break applications at scale:

• Race conditions in asynchronous UI state.
• Hydration mismatches in complex server-rendered layouts.
• Memory leaks in long-lived single-page sessions.
• Browser-specific rendering quirks that standard libraries miss.

🛠 The Solution: Big Tech Efficiency

The answers provided don't just "fix" the bug — they engineer a solution. I apply the same rigorous standards used by top-tier tech companies, focusing on:

• O(1) State Access: Optimizing data structures for instant UI feedback.
• Zero-Layout Shift: Techniques to maintain visual stability during loading states.
• Bundle hygiene: Ensuring solutions don't inflate the initial download size.

🧠 The Goal

This website serves as a living knowledge base for "unknown unknowns" — the engineering challenges you don't know you have until you hit 100k users.

🛠 Tech Stack

The platform itself is built to reflect these high standards, utilizing a modern, type-safe stack:

• Core: Next.js 16 (App Router), TypeScript
• Styling: Tailwind CSS 4
• Architecture: Server Components, Suspense Boundaries, and lazy-loaded Client Islands.
• Tooling: Biome/ESLint for strict code quality enforcement.

🔍 Code Quality Standards

This project enforces strict code quality through automated tooling:

• Linting: npm run lint (Zero-warning policy enforced)
• Type Checking: npm run check-types
• Formatting: npm run format
