Muhammad Usman

I’m a Senior Full Stack Engineer with 7+ years of experience building scalable web applications and high-performance APIs using MEAN/MERN stack. I focus on system design, production best practices, and end-to-end delivery—from architecture to release.

In recent roles, I’ve designed and developed production-grade web and mobile solutions using Node.js, React, Angular, Express.js, and NestJS, including RESTful APIs and cross-platform apps with React Native. I’ve improved MongoDB performance through indexing, query optimization, and aggregation pipelines to reduce latency, while also strengthening security with authentication and role-based access control.

I’m also hands-on with cloud deployments and reliability improvements using CI/CD, automated testing, Docker, and AWS/Linux. Beyond core engineering, I’ve integrated AI-driven features like LLMs into SaaS platforms, and I lead technical design discussions and code reviews to deliver measurable outcomes like 99.9% uptime, reduced latency, faster release cycles, and improved user engagement.
