01 — About

I turn messy
data into
sharp decisions.

I'm a Data Scientist & ML Engineer with 5 years of experience and a Master's in Computer Information Systems from Boston University (GPA 3.85). My work spans classical ML, large language models, agentic AI, and production-grade generative AI systems.

At Route Mobile I owned the full ML lifecycle — from building and monitoring Airflow-powered data pipelines to shipping customer segmentation (KMeans) and demand forecasting (XGBoost) models. I love working at the intersection of LLMs, RAG architectures, and autonomous agents.

When I'm not training models, I'm designing systems that think, reason, and act.
