About Me

Profile Picture

I'm an enthusiastic embedded systems developer with a strong foundation in C programming, Linux environments, and hands-on experience with platforms like Arduino and Raspberry Pi. I love building smart, responsive systems that bridge the gap between hardware and software.

Whether it's prototyping with microcontrollers, automating tasks using Raspberry Pi, or diving deep into low-level code and device drivers, I enjoy solving real-world problems with efficient and practical embedded solutions.

Outside of coding, I’m always exploring new tech in the embedded space, experimenting with sensors, or fine-tuning projects on the Linux command line. I believe in writing reliable, maintainable code and creating systems that are both powerful and elegant. Let's bring innovation to life—one circuit at a time!
