At GPower, I built a multi-tenant accounting web application for billing, invoices, and financial reporting. I developed invoice-to-job matching, recurring invoicing, overdue-payment tracking, and branded PDF exports.

At InfinitusInternationalFZE, I delivered commerce features for product listings, service bookings, checkout, catalog management, and order processing. I also improved customer-facing performance through code splitting, lazy loading, asset optimization, and efficient component rendering.

At Shahi KohinoorLLC, I built responsive React and Next.js applications, contributing to a 30% increase in user engagement. I developed APIs and optimized MongoDB retrieval, improving it by 40%.

I built RoleCraft, an AI platform for ATS keyword matching and resume section rewrites using OpenAI APIs and structured prompts. My work included DOCX patching, PDF rendering, live preview, and one-click resume tailoring.
