Project details
I will build a modern, responsive, and scalable MERN Stack web application using React, Node.js, Express.js, MongoDB, JavaScript, and TypeScript.
This project is ideal for businesses and startups that need a custom web application, admin dashboard, customer portal, CRM, management system, marketplace, API-driven platform, or new functionality added to an existing MERN application.
What I Can Help You Build
• Custom MERN web applications
• Admin and customer dashboards
• CRM and management platforms
• Authentication and role-based access
• REST APIs and backend services
• MongoDB database architecture
• Stripe and payment integrations
• Third-party API integrations
• Real-time functionality
• Responsive React interfaces
• AWS and cloud deployment
My focus is on clean, maintainable, production-ready development rather than simply delivering frontend screens.
For larger or complex applications, please contact me before ordering so we can confirm the requirements, appropriate package, and development scope.

Calendly API & Webhook Integration
Excellent work! Hamza quickly identified and fixed our Calendly webhook integration issues and made sure the scheduling automations were working reliably. He has strong knowledge of APIs, webhooks, and backend integrations, communicated clearly throughout the project, and delivered exactly what we needed. Highly recommended for Calendly, API integration, and full-stack development work.
