02 About

Engineer first, close to the hardware.

Joel Sebastian

I am a Mechatronics Engineering student focused on building practical systems across software, electronics, and mechanical design. I like projects where I can prototype fast, test, and iterate.

Most of my work sits close to the hardware: firmware on microcontrollers, the tooling around it, and the software that talks to it.
