BACKGROUND & ACADEMIC FOUNDATION

An engineer who likes understanding the whole system.

I'm an Electrical and Electronics Engineering student at Navrachana University in Vadodara, India. My work sits at the intersection of electronics, embedded systems, power conversion, sensing, and mechanical design.

I enjoy taking a problem from an idea or a block diagram to a circuit, a PCB, a mechanical assembly, and eventually a prototype that can be tested. My projects have included a custom three-axis PCB milling machine, a magnetic-field sensing platform, a high-frequency inverter, and a BLDC/PMSM motor controller.

Read Complete Engineering Philosophy expand_more

I learn by studying datasheets, working through circuit calculations, building prototypes, debugging hardware, and improving designs through iteration. I'm especially interested in the engineering details that connect individual components into a reliable system.

I don't consider a design complete simply because a PCB has been routed or a circuit works in simulation. Fabrication, bring-up, measurement, debugging, and validation matter just as much.
