Artifacts

Distributed Sensor Network

Hardware · Multi-Node · CAN Protocol

Engineered a multi-node CAN bus communication system with real-time sensor data exchange across ESP32, Arduino, and STM32. Focused on protocol-level control and physical implementation logic rather than high-level abstractions.

CAN Bus

ASL Converter

AI · FPGA · Embedded

An ML-powered sign language to text and audio converter deployed on an FPGA Krias Board. Designed with deep empathy, translating complex ML inference hardware into a seamless accessibility tool for immediate human use.

Accessibility

Radar System

ESP32 · Ultrasonic · UI

A comprehensive radar detection suite combining Arduino and ESP32 with a custom wireless GUI. This project established the foundation for my subsequent internship at the India Meteorological Department.
