Created an automated license renewal system with role-based access control and alerting using Microsoft Power Platform, reducing renewal time from weeks to 2–3 days and scaled for adoption across Legal, Cyber, IRM, and Compliance teams. Added data validation checks in ServiceNow security incident workflows using reference filters, classification fields, and catalog schema updates, reducing invalid and duplicate records 15% compared to the previous year. Wrote classification logic and evaluation metrics across 7 data sources, streamlining manual triage workflows for a security operations team of 55 contractors, improving incident categorization consistency.

Designed and maintained an Apache Airflow ETL pipeline to process monthly Excel HR datasets, replacing manual cleaning steps and enabling smarter workforce planning decisions by the HR team and Chief People Officer. Delivered HR dashboards analyzing workforce data across 12 departments and 1000+ employees, supporting headcount planning, diversity reporting, and leadership decisions on hiring and turnover trends. Automated statistical significance testing using Python (Chi-square and p-value computation), enabling repeatable hypothesis testing across workforce datasets for leadership reporting.

Implemented 7 clustering algorithms (KMeans, BIRCH, DBSCAN, Spectral, Fuzzy C-Means, Rep-C, GMM) for classifying users into close-friends, friends and acquaintances, validated on real-world datasets Ciao and FilmTrust. Evaluated cluster quality using 4 validation metrics including Silhouette Score, Davies-Bouldin Index, and Calinski-Harabasz Index, ensuring statistical robustness of results. Published findings in IET Communications, contributing to research on ever-changing social networks.
