About
A bit about me
Who I am, what I care about, and the path that shaped my work.
I am an Electronics and Telecommunications Engineering undergraduate passionate about building intelligent hardware at the intersection of electronics, embedded systems, and robotics. From custom PCB design to embedded control and robotic systems, I enjoy turning ideas into practical, reliable, and well-engineered products.

Micromouse Version 3 — STM32-Based Autonomous Maze Solver
Developed Micromouse Version 3 using an STM32 microcontroller, Sharp IR distance sensors, and ToF sensors. Designed velocity profiles in MATLAB for easier motion-control tuning, progressing from a hand-soldered prototype to a custom PCB, with encoder-based incremental feedback and selectable operating modes for autonomous maze navigation.

Elephant Fence Breach Detector
An Elephant Fence Breach Detector is a smart monitoring system designed to detect failures or damage in electric elephant fences. When a fence breach is detected, the system automatically sends an SMS alert to nearby villagers or responsible authorities, enabling quick action and helping reduce human–elephant conflicts.
