Usman Raja

I’m a Full Stack Developer focused on building scalable, API-driven platforms with an emphasis on performance, reliability, and clean code. I deliver end-to-end features—from backend services and APIs to responsive frontend experiences—using modern JavaScript and Python ecosystems.

In my recent role at Modern Animal, I designed and delivered full stack features with Node.js, TypeScript, React, and cloud services. I built backend APIs using RESTful APIs and GraphQL, integrated third-party APIs for real-time data synchronisation, and implemented real-time capabilities with WebSockets and event-driven patterns.

I’ve also worked as a Senior Software Engineer through Toptal, delivering full stack applications with JavaScript, TypeScript, React, Node.js, Django, and Flask. I designed scalable APIs with RESTful APIs and GraphQL, built and optimised frontend components for responsive and accessible user interfaces, and implemented scalable AWS infrastructure and deployment pipelines.

Across roles, I consistently improve systems by applying testing strategies like unit and integration testing, and by optimising backend services and frontend rendering strategies. I collaborate in product-driven environments and work closely with DevOps teams—producing technical documentation and supporting deployment and monitoring processes.
