About me

Deep expertise in large language models and generative AI, computer vision, and end-to-end MLOps. Combines strong research instincts with production discipline — shipping models that are accurate, monitored, and cost-efficient at scale — and mentors engineering teams to do the same.

Project history

Senior AI Engineer

Bell Textron Inc.
Leading a team of 5 ML engineers delivering production AI across manufacturing and supply chain, owning the full model lifecycle from research through deployment and monitoring. Architected a computer-vision defect-detection system (PyTorch, YOLOv8, Detectron2) for assembly-line inspection, reaching 98.6% detection accuracy and cutting manual QA time by 65%. Built a production RAG assistant over 40,000+ engineering and maintenance documents (LlamaIndex + pgvector + a fine-tuned open-weight LLM), reducing technician lookup time from ~25 minutes to under 2. Fine-tuned domain LLMs with LoRA / QLoRA on proprietary corpora and served them via vLLM, improving task accuracy 18% over off-the-shelf baselines while cutting inference cost 40%. Standardized an MLOps platform on AWS SageMaker with MLflow, Kubernetes, and CI/CD, reducing time-to-production for 20+ models from weeks to days.

AI / Machine Learning Engineer

Xcel Energy - Southwestern Public Service Co.
Developed deep-learning load-forecasting models (LSTM, Temporal Fusion Transformer) that cut day-ahead forecast error (MAPE) from 6.2% to 3.1%, improving grid dispatch and lowering reserve costs. Built an anomaly-detection system over 8 TB/day of smart-meter data (autoencoders + isolation forests) to flag equipment faults and energy theft, recovering an estimated $1.4M annually. Deployed and monitored models with SageMaker endpoints, automated Airflow retraining, and Weights & Biases experiment tracking.

Machine Learning Engineer

Amarillo National Bank
Built gradient-boosted fraud-detection models (XGBoost) on streaming transaction data, increasing recall 22% while reducing false positives 35%. Developed an NLP pipeline (spaCy) to classify and route customer inquiries, automating ~40% of first-line triage. Engineered a feature store and automated scoring pipelines powering credit-risk and customer-churn models.
