About
Data analyst and M.S. in Data Analytics candidate (September 2026) who takes analyses end to end — extracting and validating data from relational and NoSQL sources with SQL and MongoDB, building and comparing predictive models in Python and R, and reporting results through Power BI dashboards. Capstone work spans the full CRISP-DM cycle, including regularized variable selection, class imbalance handling, decision threshold optimization, and detection of data leakage that had inflated model performance.
Consistent emphasis on whether a result holds up: documenting assumptions and limitations, validating out of sample, and reporting what a model can and cannot support.
Background in regulated, deadline-driven environments requiring precise documentation and communication with non-technical stakeholders.
