Jihadul Amin

I’m a software engineer specializing in backend and full-stack development, with a strong focus on scalable system design, API architecture, and reliable backend services. I like building modular applications that balance clean authentication flows, solid database design, and dependable integrations.

In my projects, I’ve architected production-style backends using Django, FastAPI, and Node.js, while also shipping full-stack experiences with React. I’ve implemented JWT authentication, Stripe payments, REST API design, and role-based access patterns, and I’m comfortable making systems secure, maintainable, and observable.

I also enjoy building systems that require real-time thinking and engineering discipline. For example, I developed a Socket.io real-time messaging feature with secure encrypted chat data storage, and I worked on a ROS-based Mars rover prototype using Python, C++, and Arduino for communication and control support.

More recently, I’ve been drawn to AI-integrated systems and retrieval pipelines. I built a modular RAG-based document retrieval system (ingestion, retrieval, and query processing) with token-based chunking, vector retrieval logic, and structured logging to keep the system dependable.
