What I'm looking for

I’m looking for an environment that encourages me to succeed and grow professionally, where I can use my skills and knowledge.

At UnivisionTechnologiesPvtLtd, I worked as a Graduate Trainee on firmware, including building firmware files and adding debug statements. I also worked with Intel development boards and flashed and updated BIOS using Dediprog SF 100.

During my Advanced Embedded Systems internship, I wrote and tested C firmware for STM32 peripherals and assisted with hardware debugging and board bring-up. I also built STM32 LED projects and developed machine learning projects, including an image classifier for distinguishing AI-generated from real images.
