🚀 Engineering a High-Performance Portfolio System

The Challenge: Overcoming "Heavy" Client-Side Portfolios

Traditional React-based portfolios often suffer from bloated JavaScript bundles, leading to high Total Blocking Time (TBT) and poor Largest Contentful Paint (LCP). For a Systems Engineer, a slow site is a bad resume. This project was built to prove that a feature-rich CMS can still achieve sub-second performance.

🛠 Architectural Strategy

1. Performance Profiling & Main-Thread Optimization

Using the Chrome DevTools Performance Tab, I identified that "Evaluate Script" tasks were the primary cause of high TBT.

• The Solution: Implemented Dynamic Routing and selective Component Hydration.
• Result: Reduced the initial JavaScript payload by 40%, moving heavy interactive elements off the critical rendering path.

2. Edge-Computing & Security with jose

To avoid the latency of traditional session databases, I implemented Edge Authentication.

• Stateless Auth: Utilizing jose for JWT verification directly within Next.js Middleware.
• Secure Protocols: Admin access is governed by HTTP-only secure cookies, verified at the network edge to ensure unauthorized requests never even reach the server infrastructure.

3. SEO & Semantic Discovery

Visibility is as important as performance. This system automates the technical SEO pipeline:

• Semantic HTML: Pure Server Components ensure that search engine crawlers receive fully rendered HTML instantly.
• JSON-LD Integration: Automatically injects Schema.org structured data, allowing search engines to index the site as a professional entity.
• Metadata API: Dynamic OpenGraph and Twitter cards are generated server-side for every project slug.

📈 Impact Metrics

• Performance: 98/100 (Mobile) | 100/100 (Desktop) via Lighthouse.
• TBT: Reduced from 450ms to < 50ms.
• FCP: Sub-300ms on global 4G connections.
