Information Technology Student at ITS.
I'm interested in programming and enjoy building digital projects that help me learn, experiment, and solve real problems through code.

I'm Rayyan Ahmad Bahy Rachmandika, an Information Technology student at Institut Teknologi Sepuluh Nopember.
I learn best by shipping practical digital projects: websites, mobile app prototypes, school event systems, and AI-assisted features. This portfolio highlights the work I have built while improving my frontend, product flow, deployment, and problem-solving skills.

Studied in a science-focused environment and joined the Informatics Study Club, where I started building programming projects. I also joined technical class activities that strengthened my interest in technology and problem-solving.

Accepted through the SNBT pathway and currently studying Information Technology at ITS. I am continuing to build my foundation in programming, software development, digital systems, and technology-based projects.
