Skills

Projects

Pathfinding Algorithm Visualizer

Python, NetworkX, OSMnx, Streamlit, Matplotlib

Designed an interactive visualizer comparing Dijkstra, A*, BFS, and Bellman-Ford algorithms on real-world maps. Integrated OpenStreetMap data with caching and dynamic graph visualization for algorithm performance analysis. Added route testing and performance comparison metrics, visualizing distance, execution time, and explored nodes.
Deep Learning-Based Skin Cancer Detection with Grad-CAM (HAM-10000 Dataset)

TensorFlow, Keras, OpenCV, Python

Built a CNN-based classifier using DenseNet121 for skin lesion diagnosis on the HAM10000 dataset, achieving greater than 93% accuracy. Applied targeted data augmentation to address severe class imbalance across seven lesion types. Implemented Grad-CAM visualizations for explainability, validating the model’s focus on relevant lesion regions. Optimized training with stratified data splits and weighted loss functions for balanced performance.
Fine-Tuned Speech Recognition System with OpenAI Whisper

PyTorch, Transformers, Librosa, Gradio

Fine-tuned OpenAI Whisper on LibriSpeech for English speech-to-text transcription, achieving approximately 90% accuracy (10.4% WER). Built an interactive Gradio web interface supporting GPU/CPU auto-selection for real-time inference. Implemented mixed-precision training, gradient accumulation, and a custom DataCollator for sequence padding efficiency.
Sarcasm Detection in Gujarati Language

Python, Hugging Face Transformers, IndicBERT, PyTorch

Developed a sarcasm detection model for Gujarati text using the IndicBERT transformer, fine-tuned on regional-language datasets. Preprocessed data with tokenization, transliteration normalization, and text cleaning to handle Gujarati-specific linguistic variations. Evaluated model performance using precision, recall, and F1-score to ensure robust sarcasm classification in low-resource language contexts.
Fairness Analysis of Face Recognition Models Under Environmental Degradations

Python, PyTorch, ArcFace, AdaFace, OpenCV, Grad-CAM

Conducted fairness evaluation of state-of-the-art face recognition models (ArcFace and AdaFace) across demographic subgroups under varying environmental degradations such as brightness changes and pose rotations. Analyzed recognition performance disparities using metrics including verification accuracy, false acceptance rate (FAR), and false rejection rate (FRR) to identify demographic bias patterns. Implemented Grad-CAM based visual explainability techniques to interpret model attention regions and investigate failure cases under challenging real-world conditions.
