Mohd Hasan

I am a passionate and results-driven Backend Developer with experience in building secure, scalable, and efficient web applications using Node.js, Express, MongoDB, Redis, and related technologies. I thrive on solving complex problems and designing systems that are both robust and maintainable. In my recent project, I developed a production-ready LMS backend featuring JWT authentication with Redis-backed refresh tokens, role-based access control, multi-step course review workflows, secure Cloudinary file uploads, background job processing with BullMQ, and anti-cheating mechanisms for video progress tracking. I ensured atomicity and consistency through MongoDB transactions, implemented idempotent admin actions, and optimized API performance with caching and short-lived signed URLs. I am deeply interested in building scalable systems, designing clean architectures, and continuously learning new technologies to improve application reliability, security, and performance. My approach balances technical excellence with practical solutions, keeping user experience and real-world constraints in mind. I enjoy collaborating in teams, writing clean and maintainable code, and documenting systems clearly to ensure knowledge sharing. I am motivated by challenges where I can apply my backend expertise, troubleshoot complex issues, and contribute to impactful projects. I am looking for opportunities to work on backend development, system design, and scalable applications, where I can leverage my skills to build robust, high-performance systems while continuing to grow as a software engineer.
