Mutasim Fuad Rimu

Full-stack engineer & security researcher

I'm a full-stack engineer from Kushtia, Bangladesh. I design and build web applications end to end — from the database schema and API down to the last detail of the interface — with a strong bias for software that is fast, private and hard to break.

Alongside engineering I do research at the meeting point of deep learning and security. My M.S. work explored how neural networks can make physical-layer secret key generation more reliable in FDD wireless systems.

Background

I recently received my Master’s degree from Changchun University of Science and Technology (CUST) in 2026, where my research was conducted under the supervision of ADHoc Fellow Prof. Chunyi Chen. Before, I earned my Bachelor’s degree in Computer Science and Technology from Nanjing University of Information Science and Technology (NUIST) (Binjiang College) in 2024, under the supervision of Prof. Lou Qianda.

My academic work centers on Cybersecurity and Physical Layer Security, specifically optimizing secret key generation in FDD systems utilizing Deep Learning architectures. During my undergraduate studies, I published my thesis titled "Design and Implementation of a Potato Disease Classification System Based on Deep Learning". Parallel to my academic research, I professionally architect secure, privacy-centric web applications and explore the synergy between neural networks and secure communication protocols.

next-store

I developed a full-stack, high-performance e-commerce platform designed for speed and scalability. Built on Next.js and React, the application features a robust custom authentication system (JWT) with automatic admin-role assignment, and it utilizes Drizzle ORM to interface seamlessly with a MySQL database. The platform provides a rich user experience with dynamic product listings, a comprehensive shopping cart, and seamless checkout flows. On the administrative side, it includes a secure, feature-rich dashboard for managing products, tracking orders, creating flash deals, and applying bulk discounts. To ensure maximum global performance and edge-caching, the entire application is optimized and deployed via Cloudflare Workers.

Purge Chat

Purge Chat is a real-time chat application built around short-lived rooms and disappearing conversation history. It is designed for private, temporary exchanges where the conversation should not remain available indefinitely. The app combines live messaging, room expiration, owner-controlled backup, and client-side encryption so that a room can be used for a limited window and then disappear cleanly.

Beyond the screen

Away from the keyboard, my heart belongs to football — I manage Duranta Club Nitailpara in my hometown. I also love capturing photos and videos, writing, looking after the garden, and slowing down to enjoy Allah's creation with my family.
