Niral P.

I am a Senior Embedded Systems Engineer with 19+ years of experience in Embedded Firmware Development, PCB Design, and IoT Product Engineering. I help startups and businesses develop production-ready embedded products from concept to manufacturing. I specialize in building reliable, scalable, and manufacturable embedded systems for industrial automation, smart home systems, wearable devices, medical electronics, and consumer products. I have successfully delivered complete embedded and IoT solutions covering hardware architecture, schematic design, firmware development, wireless connectivity, PCB layout, testing, and production support.
