I'm a Computer Science Engineering (IoT) undergraduate, expected to graduate in July 2027, with strong fundamentals in data structures, algorithms, AI/ML, networking, and full-stack web development.
My work spans production Next.js and MERN platforms, REST APIs, Docker and CI/CD workflows, CNN model training, and edge-cloud AIoT systems with Raspberry Pi, Flask, OpenCV, and React dashboards. I have interned with Tellis Technologies, built fintech features for Celeriz, and led multiple AI-driven team projects.
