ABOUT ME

>> Origin: Earth | Sector: Developer Quadrant | Status: Active

Background

As a second-year ECE student at UWaterloo, I build scalable, innovative solutions at the intersection of software development, AI, machine learning and embedded systems.

Beyond tech, I enjoy learning about philosophy, cognitive science and astrophysics. A fun fact about me: I published my first short story with Polar Expressions Publishing at age seven! In my free time, I practice calligraphy and read dystopian fiction.

AssistWave - STM32CubeIDE Medical Assistive Device

An ultrasonic sensor is used to track hand movements within predefined distance thresholds. An STM32 microcontroller transmits this data via UART communication in Single Wire Half-Duplex Mode to a receiving STM32 Nucleo board over a 1-meter wired connection. Based on the received data, output actions are triggered, such as turning on an LED light, activating a fan, and operating servo motors to open doors.

Fine-Tuned Sentiment Analysis with LoRA and DistilBERT

Movie review sentiment analysis using a fine-tuned DistilBERT transformer model. The model is trained and evaluated on the IMDb dataset with Hugging Face’s Transformers library and accelerated with CUDA on an NVIDIA GeForce RTX 4060 Laptop GPU. Fine-tuning is performed using Low-Rank Adaptation (LoRA) with Parameter-Efficient Fine-Tuning (PEFT), integrated into Hugging Face’s Trainer API. Inference is deployed through a Streamlit web application displaying predicted sentiment labels (positive/negative), confidence scores and runtime device information (CPU/GPU).
