About

ECE graduate and Embedded Systems Engineer with hands-on internships at Vizag Steel Plant (RINL), Blackbuck Engineers, and NITK-STEP. Builder of 7 hardware prototypes spanning embedded security, RF antenna design, IoT monitoring, accident detection, and smart card systems — across Arduino, ESP32, Raspberry Pi, and STM32 ARM Cortex platforms.

Quantum-certified through MeitY's DST-NQM programme. Actively seeking embedded systems roles working with ARM Cortex, RTOS, and industrial-grade platforms.
