Next.js Full-Stack Developer | SaaS, Ecommerce & Business Applications
Karachi, Pakistan - 8:49 pm local time
I’m a Full-Stack Developer specializing in Next.js application development, custom business systems, ecommerce automation, API integrations, and custom/headless CMS platforms.
Recent work includes integrating Zoho APIs with custom applications and payment gateways, automating ecommerce workflows from cart to payment, order processing, Zoho invoicing and email notifications, and building rule-based systems for coupons, pricing, tax, shipping, product eligibility, order approval, and geographical conditions.
I’ve also built custom CMS tooling capable of managing most of an ecommerce site's content, complex nested product/category structures, dynamic data tables, caching and revalidation systems, and lightweight event-based synchronization for real-time cart updates without unnecessary client-side rendering.
========================================
======== What I can build or improve ==========

◉ Next.js & React SaaS applications
◉ Custom ecommerce platforms and automation
◉ Headless and custom CMS systems

◉ Payment gateway integrations
◉ Admin panels, dashboards, CRM and business portals
◉ Database design and application architecture
◉ Existing Next.js upgrades and modernization
◉ Feature development and long-term maintenance
◉ Technical SEO and Core Web Vitals optimization
◉ Performance and rendering optimization
◉ React Native Android applications
========================================
========= My engineering approach ==========
========================================
◉ Performance is not something I add at the end of a project.
◉ I consider LCP, FCP, CLS, JavaScript execution, rendering strategy, caching, database queries, dependencies, scalability, and maintainability while designing the application.
◉ I generally prefer SSR and server-side execution where appropriate, minimize unnecessary JavaScript and client-side rendering, and carefully evaluate dependencies before introducing them into a project.
◉ The goal is not simply to make an application work. It is to make it efficient, maintainable, scalable, and practical to operate.
◉ I’ve delivered 40+ projects for clients across the USA, UK, Europe, and the Middle East, covering SaaS platforms, multilingual applications, CMS systems, CRMs, ecommerce platforms, dashboards, lead-generation websites, and custom business applications.
◉ If you have an existing application that needs new features, modernization, integrations, performance improvements, or a new product that needs to be built from the ground up, I can help turn the requirements into a production-ready system.
