Embedded hardware design engineer building reliable IoT and sensor products.

What I'm looking for

I’m looking for an embedded hardware role where I can build reliable IoT/sensor products end-to-end—owning schematic-to-prototype work, debugging/testing/validation, and collaborating with cross-functional teams to deliver production-ready hardware.

I’m an Embedded Hardware Design Engineer focused on end-to-end hardware product development—from concept to manufacturing. I bring strong expertise in digital and analog circuit design, schematic design, component selection, PCB development, prototyping, and reliability-driven debugging, testing, and validation.

At Dayro Pvt Ltd (April 2024–present), I worked on IoT hardware and sensor integration “from the ground up,” covering integration, prototyping, extensive testing, and close cross-functional collaboration. I developed four complete hardware products including IoT hardware, sensor modules, custom embedded PCBs, and AC-DC & DC-DC converter designs—driving design optimization through detailed testing and validation. Earlier, as an Embedded Engineer at Disney Coding (Sept 2023–Mar 2024), I designed embedded and robotics solutions using STM32, Arduino, ESP32, and ESP8266, implemented communication protocols (I2C, SPI, UART), and developed low-level drivers to ensure reliable performance.
