• Built a multi-agent OCR pipeline bridging unstructured documents to structured data, achieving ~97% extraction accuracy — a 93% improvement over traditional OCR — with human-in-the-loop escalation limited to ~4% of cases.
• Reduced document processing costs by ~80% by replacing Vision LLMs with an optimized agentic architecture, processing 500-page documents in ~1.5 hours at ~$1 per document using cloud models.
• Developed an intelligent document search and retrieval system surpassing baseline RAG approaches, validated with strong retrieval and grounding metrics.

• Collected a medical gait dataset using a ₹4L Xsens MTw Awinda IMU kit, capturing stair ascent/descent motion from tailbone, knees, and feet.
• Built Python data pipelines to clean IMU signals and extract time- and frequency-domain features (FFT, IQR, mean, median).
• Applied unsupervised clustering (K-Means, Agglomerative, Spectral) for BMI and weight-based classification, with agglomerative clustering performing best and weight-based labels outperforming BMI in several cases.

• Owned the FastAPI-based Python backend, building and running production APIs for Scope 3 carbon emissions prediction with real-time and batch inference.
• Designed normalized tables to store emission data and built a vector-based semantic search engine using NLP techniques like NER and word embeddings, hitting ~99% retrieval accuracy on sustainability data.
• Built and deployed stacked ensemble models with TensorFlow & Keras following clean ETL and preprocessing pipelines, consistently achieving 99%+ accuracy and strong F1 scores in production.
• Created advanced Excel carbon accounting tools with heavy edge-case handling — hidden source tables, locked formulas, complex queries, and embedded regression models for precise reporting.
