The story behind the data.

I'm a Data Analyst & ML Engineer based in Boston, with 3+ years of turning complex, multi-source data into business-ready insights and predictive models.

Currently at CSG International, I work across healthcare and fraud analytics — designing ETL pipelines, deploying Power BI dashboards, and supporting predictive risk-scoring models that have driven real business outcomes.

Before that, I automated KPI/SLA reporting at Ciena using Alteryx and Python — saving the team ~$250K annually.

I just finished my MS in Data Analytics Engineering at Northeastern University, where I worked on ML projects spanning medical imaging, recommendation systems, and full-stack web platforms.
