Architecting Solutions Line by Line
I am a passionate final-year IT undergraduate specializing in Information Technology and machine learning. My engineering philosophy centers on translating complex operational requirements into clean, modular, and high-performance software.
My hands-on experience as a Trainee Software Developer at the Ministry of Finance (ITMD) allowed me to deploy and maintain government-scale platforms. I design scalable backends using Java Spring Boot alongside responsive, state-driven user interfaces leveraging the MERN stack.
