πŸ‘‹ About Me

I'm a final-year Computer Science student who likes taking ML ideas from paper to working, deployable systems. My work sits at the intersection of computer vision, retrieval-augmented generation, and multimodal learning, backed by a full-stack background so I can ship what I build.

Three DOI-archived preprints on Zenodo, covering RAG robustness, medical VQA, and mental-health NLP.

DOI RobustRAG
Empirical study of corpus poisoning and query embedding noise in retrieval-augmented QA (BGE + FAISS, SQuAD 1.1). Query noise dominates over poisoning at the tested settings, and a common near-duplicate suppression defense shows a structural failure mode.
DOI MedInsight
Does retrieval augmentation (CLIP + FAISS) improve a BLIP-2 vision-language model on medical VQA? Benchmarked on VQA-RAD and ROCOv2.
DOI AI-Based Depression Detection
Fine-tuned DistilBERT + BiLSTM with attention for detecting depressive symptoms in social media text: 91.09% accuracy with interpretable predictions.
