👋 Who am I?
I am a Computer Science student with a passion for understanding how things work under the hood—from electrical signals and memory management to modern web frameworks. My journey combines practical experience in IT Support & Systems Administration with a deep interest in Low-Level Programming (Rust/C++) and Security.
I believe in the “Growth Mindset”—I treat every error log as a lesson and every bug as a puzzle waiting to be solved. Currently focused on mastering the Rust ecosystem for web and system applications.
