About

I’m a data scientist and machine learning engineer with 3 years of production experience, completing my MS in Data Analytics at George Mason University in December 2026 with a 4.0 GPA. At Unifynd Technologies, I built and deployed ML systems end to end. 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. Recently 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. Skills: 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. Open 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.
