I’m a Web Developer with over 4 years of experience building modern, scalable, and responsive web applications. I focus on clean design implementation, performance optimization, and maintainable code.

In my current independent work, I developed an FBR-compliant sales invoicing and sales return system using React.js. I implemented JWT-based authentication/authorization, automated invoicing/returns and tax calculations, and integrated invoice APIs with secure, synchronized storage—along with PDF generation and SMTP email notifications using nodemailer.

Previously, I built Next.js + TypeScript experiences including responsive dashboards, e-commerce flows, and customer portals. I also delivered features like product barcode generation, purchase and inventory updates, inline editing and drag-and-drop interactions, and Next.js rendering optimization (SSG, ISR, CSR, SSR) to improve load times and user experience.
