Modern React Portfolio Website

Overview

Developed a state-of-the-art portfolio website showcasing modern React development practices using the latest technologies including React 19, TanStack Start, and cutting-edge tooling. The project demonstrates full-stack capabilities with type-safe routing, server functions, and advanced UI interactions.

The Challenge

Cutting-Edge Technology: Implement latest React 19 features and TanStack Start framework
Type Safety: Ensure complete TypeScript integration from database to UI
Performance: Create smooth animations and optimal loading experiences
Modern Architecture: Build a scalable, maintainable full-stack application
Developer Experience: Establish excellent tooling and development workflow

Technical Approach

Full-Stack React Architecture

Built using TanStack Start for modern full-stack React development:

// Server function for case study data fetching
export const getCaseStudies = createServerFn({
  method: "GET",
}).handler(async (): Promise<CaseStudy[]> => {
  const caseStudies = await getAllCaseStudiesFromDB();
  return caseStudies.sort(
    (a, b) => new Date(b.date).getTime() - new Date(a.date).getTime()
  );
});

// Type-safe route definition
export const Route = createFileRoute("/case-study/$id")(
  {
    component: CaseStudyComponent,
    loader: async ({ params }) => {
      const caseStudy = await getCaseStudy(params.id);
      if (!caseStudy) throw notFound();
      return caseStudy;
    },
  }
);

Advanced Animation System

Implemented sophisticated scroll-based animations and section detection:

// Intelligent section visibility detection
const calculateActiveSection = useCallback(() => {
  let maxVisibility = 0;
  let currentSection = "";

  SECTIONS.forEach((section) => {
    const element = document.getElementById(section.id);
    if (!element) return;

    const rect = element.getBoundingClientRect();
    const visibleTop = Math.max(0, rect.top);
    const visibleBottom = Math.min(window.innerHeight, rect.bottom);
    const visibleHeight = Math.max(0, visibleBottom - visibleTop);
    const visibilityRatio = visibleHeight / rect.height;

    if (visibilityRatio > maxVisibility) {
      maxVisibility = visibilityRatio;
      currentSection = section.id;
    }
  });

  setActiveSection(currentSection);
}, []);

Modern CSS with Tailwind v4

Utilized latest Tailwind CSS v4 with custom animations:

@keyframes wave {
  0%, 100% { 
    transform: rotateZ(0deg) rotateY(0deg); 
  }
  50% { 
    transform: rotateZ(15deg) rotateY(10deg); 
  }
}

.animate-wave {
  animation: wave 3s cubic-bezier(0.4, 0, 0.6, 1) infinite;
  transform-origin: 70% 70%;
  transform-style: preserve-3d;
}

.animate-gradient {
  background-size: 200% 200%;
  animation: gradient 8s ease infinite;
}

Database Integration with Node.js SQLite

Implemented native Node.js SQLite integration with automatic seeding:

import { DatabaseSync } from "node:sqlite";

export function initializeDatabase(): DatabaseSync {
  let db: DatabaseSync;
  
  try {
    db = new DatabaseSync("portfolio.db");
  } catch (error) {
    console.warn("Falling back to in-memory database");
    db = new DatabaseSync(":memory:");
  }
  
  // Create tables and seed data
  db.exec(`
    CREATE TABLE IF NOT EXISTS case_studies (
      slug TEXT PRIMARY KEY,
      title TEXT NOT NULL,
      description TEXT NOT NULL,
      content TEXT NOT NULL,
      date TEXT NOT NULL,
      featured INTEGER DEFAULT 0
    )
  `);
  
  return db;
}
