Project details
I will build a modern, scalable full-stack web application using React, Next.js, Node.js, TypeScript, JavaScript, REST APIs, PostgreSQL, MongoDB, Supabase, and cloud technologies. Whether you need a custom business application, customer portal, marketplace, booking platform, internal tool, management system, membership website, analytics application, or startup product, I can develop the complete solution from frontend to backend.
Your web application can include responsive UI development, authentication, user accounts, role-based access, database architecture, REST API development, third-party API integration, payments, file uploads, search, notifications, admin functionality, real-time features, and AWS or cloud deployment.
I work across the complete development stack, connecting frontend interfaces with backend services, databases, APIs, and server-side business logic. My focus is clean code, performance, security, responsive design, maintainable architecture, and production-ready development. You receive a complete web application designed around your business requirements and built to support future features, integrations, users, and product growth.

WordPress Website Speed Optimization, Core Web Vitals, Elementor Pro & PHP Performance Fixes
Shahzad did a great job optimizing my WordPress/Elementor website. I was facing several speed and performance issues, including slow loading, low PageSpeed score, Core Web Vitals problems, image optimization issues, and unnecessary CSS/JavaScript loading.
He reviewed the website carefully, optimized the main performance areas, improved the loading speed, and kept the design, layout, forms, and content unchanged. He completed the work in less than 24 hours and communicated clearly throughout the project.
I would recommend Shahzad to anyone looking for a professional WordPress and Elementor developer for speed optimization and performance improvements.
