Hey there, I'm

Reza Andyah Wijaya

People call me Bang Ejak. (I know, what kind of name is Ejak, right?)

I'm a Software Engineer who lives for complexity. I spend my days building robust systems and my nights — or classrooms — teaching others how to do the same. I have an eye for design, but my heart is in the logic.

What I Do

Build

I architect and build robust software systems — from APIs to full-stack web apps. I care about code that scales, not just code that runs.

Teach

I break down complex engineering concepts in the classroom and online. Making the hard stuff click for others is the most rewarding work I do.

Learn

I'm a perpetual student. Whether it's a new framework, a design pattern, or an entirely different domain — I stay hungry.
