ABOUT ME

Christian Jay Mandani Profile Photo

Back in my senior high school years, I learned HTML, CSS, and Bootstrap, which sparked my deep passion for web and system development. My very first Hello World program was written in the Java programming language.

Now in college, I’ve expanded my technical toolkit to include C++, Java, and Python, while specializing primarily in JavaScript and TypeScript for web applications, as well as Dart and Flutter for mobile development.

I live with a physical condition called clubfoot in my right foot—yet I perform everything normally. It serves as a continuous reminder of my resilience, drive, and determination to conquer every goal in life.

When I’m not coding, I enjoy watching movies, K-dramas, or anime, listening to music, and constantly exploring emerging web technologies and building side projects.
