Fajar Geran Arifin

Backend Developer & System Engineer

I am an Informatics Engineering student currently working as a Developer at PT. Novatech Solution, alongside joining an IT internship program at Padud Jaya. My main interests are backend development, internal company systems, and system security. My journey in programming started in high school during the pandemic, when I began self-learning technologies like Python and HTML. Over time, my interests expanded into ethical hacking and artificial intelligence. During college, I joined the ethical hacking specialization group (JKF) and explored AI by building chatbots, expression systems, and Gemini API integrations. I am currently preparing AI support for my final research in system security. I enjoy the process of understanding code structure, system logic, and infrastructure management, especially on systems that require high stability and security.
