About

ECE graduate who turns circuit-level ideas into working firmware. Currently developing real-time embedded systems at SmartBuild Automation using ESP32-S3, FreeRTOS, and a full suite of wireless protocols.

I don't just write code — I debug UART traces at 3AM, calibrate industrial sensors to µA precision, and chase down RF interference with an oscilloscope. From MQTT device control to multimodal medical imaging with MATLAB — I build things that work in the real world.

Live — FreeRTOS Task Scheduler Simulation

FreeRTOS uses a preemptive scheduler where higher-priority tasks preempt lower ones. Each colored bar represents a concurrent task (UART_TX, WIFI_HANDLER, BLE_SCAN, SENSOR_READ) running on the ESP32-S3's dual cores.
