Who I Am

I'm an Electrical Engineering student with a deep passion for bridging the gap between analog hardware and digital intelligence. Based in Indonesia, I design circuits that don't just work — they're elegant.

"First, solve the problem. Then, write the code." — John Johnson

My focus lies in embedded systems design, power electronics, and IoT applications. I believe great engineering comes from understanding a system from electrons up to the application layer.

When I'm not designing PCBs or debugging firmware, I'm contributing to open-source hardware projects or exploring the intersection of machine learning and embedded systems (TinyML).

Let's Connect

Have a project in mind, want to collaborate on hardware design, or just want to talk electronics? I'm always open for a good conversation about circuits and embedded systems.
