Paladin (Oathbreaker) Class & Subclass

Chaotic Lawful Alignment

Human Race

Who am I?

I'm Ong Gabriel Riverine Susanto, also known as Riveong. I'm an adventurous software engineer and an ex-2023 Bangkit Academy cohort.

As a bachelor of informatics, I have a strong passion in software engineering. I am a lover of tech and all its wonders. I marvel at the power of backend development, mobile apps, UI/UX, and the infinite possibilities they offer. I delight in learning new things and expanding my horizons. I cherish writing, debugging, problem-solving, and working under pressure as art forms of expression and creativity.

Why the D&D Oathbreaker Paladin? Much like a Paladin who broke their oath to forge their own path, I believe in breaking standard conventions in technology. Being "Chaotic Lawful" represents my philosophy: coding requires strict logical discipline (Lawful), but solving complex problems often demands creative, outside-the-box disruption (Chaotic).
