An engineering mindset. A drive to build.
I’m pursuing a B.E. in Electronics and Communication Engineering at V.S.B. College of Engineering Technical Campus, Coimbatore, with a CGPA of 9.45/10.
My interests span embedded systems, electronics, communication systems, and semiconductor technology. Through internships at Codtech IT Solutions and Feather Softwares, I have developed Arduino projects, worked with sensor data, and built interactive dashboards. I use Python and Java in my programming work and am currently learning VLSI and digital design fundamentals as part of my academic curriculum.
Open to internship opportunities and technical projects where I can learn, contribute, and apply engineering concepts to practical problems.
A strong foundation. Always learning.
