About Muhammad Ahmed
I’m a backend-focused full-stack developer specializing in Node.js, Express.js, MongoDB, PostgreSQL, NestJS, and .NET Core — with production experience delivering scalable web and mobile applications. I help startups, SMEs, and tech teams build fast, clean, and maintainable backend systems with strong architecture, secure APIs, and real-time features like messaging and geolocation.
I’ve worked on a range of high-impact projects:
Medicare: a medical logistics app built for the Saudi government to track restricted medicine deliveries from hospitals to patients, using .NET Core and MVC.
BaadMay: a Buy Now Pay Later (BNPL) platform for e-commerce, built with Express.js and SFCC.
Kasssh: a cash-based payment gateway integrated with 28,000+ physical stores.
NewEcomAI: an AI-powered shopping platform offering personalized recommendations using a React + Node.js PWA.
Helpsta (ongoing): a geolocation-based mobile app connecting neighbors to request and offer help, using NestJS, PostgreSQL, Socket.IO, and React Native.
I follow clean architecture principles, prioritize code readability and scalability, and bring strong experience in API development, database modeling, third-party integrations, and backend security. I’m also comfortable working across the stack when needed — especially in React.js or React Native projects.
If you need a backend developer who can design from scratch, jump into existing systems, and deliver production-ready features with speed and reliability — I’d love to talk.
