Background

About Me

I am Raffael Putra Hermawan, known as Ell —a 15-year-old student pursuing dual expertise in Cybersecurity and Python Development simultaneously. I am currently in Grade 10, Semester 2, committed to self-driven growth in technology.

My journey began in Grade 7 when I first discovered programming through Termux on Android —experimenting with scripts before I fully understood what I was doing. That curiosity evolved in Grade 8, when the video game Watch Dogs 2 introduced me to the world of cybersecurity and inspired me to explore how real systems are analyzed and tested.

Since then, I have committed to continuous self-learning through online courses, competitions, certifications, and hands-on experimentation. My studies span programming, advanced networking, Linux administration, wireless security, and offensive security research.

On March 9, 2026, I formally began applying my skills in legal and responsible cybersecurity practice —committed fully to ethical principles and responsible disclosure.

Work &Experiments

Projects

I have worked across a range of project types —from experimental builds and learning exercises to open-source contributions and private commercial work. Every project, including those that failed, has been a structured step in developing real competence.

Open-Source Projects
Publicly available tools, scripts, and utilities built primarily with Python. Viewable on GitHub.
Private Projects
Commercial and confidential projects not displayed publicly. Available for review with appropriate agreements.
Learning Projects
Experimental and educational builds. Many failed intentionally —each failure provided structured knowledge.
Ongoing Research
Active exploration of wireless protocols, network analysis, and offensive security techniques.
