About
I’m Muhammad Obaid Ullah, a full-stack developer who enjoys building and maintaining production-ready web applications end-to-end—UI, APIs, and database systems. I work primarily with React and Next.js on the frontend, and FastAPI with PostgreSQL/Supabase on the backend, with a strong focus on clean architecture, debugging, and reliable integrations.
Across recent freelance and contract work, I’ve delivered real business software including a full-stack financial accounting system and a corporate B2B platform. I’m comfortable shipping features such as RBAC and audit trails, voucher and reporting workflows, and exportable financial documents, while also improving performance and user experience with responsive, component-driven React development.
