I build end-to-end AI systems — from volumetric medical-image segmentation with vision transformers, to Transformer architectures for low-resource translation, to retrieval-augmented generation pipelines in production. I care about measured metrics, reproducible pipelines, and systems that actually ship.

- Built a RAG-based search system using LangChain and ChromaDB for internal document retrieval.
- Improved data ingestion speed by 40% using recursive text splitting.
- Developed a cosine-similarity feedback loop to monitor retrieval quality, reaching 90% answer accuracy.
- Processed and managed a database of 5,000+ educational documents for automated student support.
PyTorch · MONAI · Vision Transformers
3D segmentation pipeline using UNETR on the BTCV dataset. HU-scaling on DICOM/NIFTI files, Dice-Cross Entropy loss for class imbalance. Result: Mean Dice 0.82 across 13 organs.
PyTorch · Transformers · Gradio
43M-parameter Transformer built from scratch (no nn.Transformer) on 500k AI4Bharat Samanantar pairs. Byte-level BPE, Noam schedule, length-normalized beam search, Gradio demo with cross-attention heatmaps.
Result: BLEU 16.93 · chrF++ 41.58 · TER 71.41 (beam-4, held-out 5k test).
