2026 Perspective

The Technical DNA

This is where the "Architectural Engineer" was actually born. While these years lack a formal portfolio page, they represent a decade of curiosity—from disassembling Pentium CPUs in 2009 to investigating web vulnerabilities in 2017. These fragments are the insurance policy for my current work; I don't just know how code works, I know how the system *breathes* because I've been tinkering with its lungs for over 15 years.

THE ROOTS

Circa 2009 — 2020

// The Early Seeds (SD)

It began in 2nd grade with hardware — taking apart legacy Pentium 2 systems. By 3rd grade, the hardware curiosity turned into digital consistency. Writing tips and tricks about computer optimization on Blogspot.

Google AdSense experimentation Free software distribution hub Visual Design & 3D Modeling (Blender/Sketchup)

// The Investigation (SMP)

Expanding to Kaskus and Facebook. Learning Meta Pixel and digital marketing before it was a mainstream career. Customizing Blogspot scripts led to a deep dive into WordPress.

This period introduced the "darker" side of the web: security research, dorking, and understanding vulnerabilities from the inside out — a period that built my deep technical intuition.

PHP / WordPress Themes Web Vulnerability Research Social Engineering & Scripting

// The Formalization (SMK)

Entering Computer and Network Engineering (SMK). Structural understanding aligned with years of ad-hoc tinkering. Moving beyond PHP into modern frameworks.
