My invoice recognition system, a graph neural network I trained from scratch in PyTorch, raised extraction accuracy from 48% to 78% on 10,000+ invoices a month and reduced manual review from 10 people to 3. I also built churn and retention forecasting, RFM customer segmentation, and recommendation models with XGBoost on 100,000+ customer records, and automated reporting dashboards that cut weekly reporting from 4 hours to 1.\nRecently I’ve focused on LLMs: comparing GPT-4o against fine-tuned DistilBERT for named entity recognition with evaluation rubrics, building RAG pipelines with embeddings and vector retrieval, and creating LangChain agents.\nSkills: Python, SQL, PyTorch, TensorFlow, scikit-learn, XGBoost, graph neural networks, NLP, LLMs, RAG, LangChain, A/B testing, causal inference, dbt, Airflow, Databricks, PySpark, AWS, Tableau, Power BI.\nOpen to Data Scientist, ML Engineer, and Applied AI roles in entire USA, or remote. Available January 2027. On F-1 OPT; eligible to STEM OPT, will need H-1B sponsorship.","location":"Fairfax, United States","company":"George Mason University","role":"Graduate Teaching Assistant","open_to":"Data Scientist, Data Analyst, Machine learning Engineer, Business Analyst","languages":null,"skills":["Python","SQL","MongoDB","Pandas","NumPy","scikit-learn","XGBoost","PyTorch","TensorFlow","Hugging Face Transformers","LangChain","Power BI"],"positions":[{"title":"Graduate Teaching Assistant","company":"George Mason University","location":"Fairfax, United States","start_year":2026,"start_month":1,"end_year":null,"end_month":null,"description":"Hold weekly office hours for undergraduates, walking them through course concepts and assignments.
