Research Data Intelligent Solutions | May 2022 – Present NLP and Generative AI Projects• Fine-tuned LLaMA 2 with QLoRA on SageMaker for low-memory inference on OCR-processed arbitration documents. Enabled fast, accurate extraction of liability, damages, and award decisions, recovering $500K across 730 claims and reducing manual review by 70%.• Led a scalable NLP pipeline using RoBERTa to extract and consolidate claim cost components—rental, towing, labor, parts—from noisy OCR’d subrogation documents. Applied sliding window with context-aware aggregation, improving entity accuracy by 25% and enabling $1M+ in recoveries over 100K claims.• Built a document understanding pipeline for Total Loss Valuation Reports using LayoutLMv3 for field extraction and RAG for retrieving rationale. Achieved 95%+ field-level accuracy and automated settlement review, reducing audit time and costs.• Developed a high-throughput classification system using OCR text, Titan embeddings, and a 2-layer MLP to classify rental, towing, inspection, damage, and total loss docs. Achieved 0.93 F1-score and scaled async pipelines to process millions of docs.• Architected a towing receipt classifier using Textract OCR, n-gram features, and XGBoost, reaching 98% accuracy. Computer Vision Projects• Boosted airbag deployment detection by 17% using MobileNetV2 and CNNs, saving $600K/year and preventing 1M+ unnecessary claims.• Built a vision transformer classifier with 78% accuracy on authentic vs. AI-manipulated images.• Reduced false positives by 45% and increased precision 6% using a U-Net-based reflection suppression system. Full Stack Development• Built a training system and budget tool using Django and Vue.js, improving onboarding, reporting, and planning.
