Implemented eager loading with `with()` and chunk processing with `lazy()` to optimize the query.

use App\Models\Post;

$posts = Post::with('comments')->lazy(100);
foreach ($posts as $post) {
    echo $post->title . ' (' . $post->comments->count() . ' comments)';
}

Outcome: Reduced query execution time by 40% and memory usage by 30%.

Implemented caching middleware using Next.js Edge Middleware and Redis to cache API responses.

import { NextRequest, NextResponse } from 'next/server';
import Redis from 'ioredis';

const redis = new Redis();

export async function middleware(req: NextRequest) {
  const cachedResponse = await redis.get(req.url);
  if (cachedResponse) {
    return new NextResponse(cachedResponse, { status: 200 });
  }

  const response = await fetch(req.url);
  const data = await response.text();

  await redis.set(req.url, data, 'EX', 3600); // Cache for 1 hour
  return new NextResponse(data, { status: response.status });
}

Outcome: Reduced server load by 50% and improved API response times for repeated queries.

Built a dynamic form generator that reads JSON configurations and renders forms with validation.

import React, { useState } from 'react';

const formConfig = [
  { label: 'Name', type: 'text', name: 'name', required: true },
  { label: 'Email', type: 'email', name: 'email', required: true },
  { label: 'Age', type: 'number', name: 'age', required: false },
];

export default function DynamicForm() {
  const [formData, setFormData] = useState({});

  const handleChange = (e) => {
    setFormData({ ...formData, [e.target.name]: e.target.value });
  };

  const handleSubmit = (e) => {
    e.preventDefault();
    console.log(formData);
  };

  return (
    <form onSubmit={handleSubmit}>
      {formConfig.map((field) => (
        <div key={field.name}>
          <label>{field.label}</label>
          <input
            type={field.type}
            name={field.name}
            required={field.required}
            onChange={handleChange}
          />
        </div>
      ))}
      <button type="submit">Submit</button>
    </form>
  );
}

Outcome: Reduced development time for form-based features by 70% and improved code reusability.

Utilized Laravel Sanctum to create a secure token-based authentication system.

// Sanctum setup in Laravel
php artisan require laravel/sanctum
php artisan vendor:publish --provider="Laravel\Sanctum\SanctumServiceProvider"
php artisan migrate

// Enable SPA Authentication in middleware
use Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreStateful;

protected $middlewareGroups = [
    'web' => [
        EnsureFrontendRequestsAreStateful::class,
    ],
];

Outcome: Improved security and simplified authentication process for single-page applications.
