   Contributed to defining the business problem of automating name screening against global watchlists (OFAC, EU, UN) using Natural Language Processing (NLP) and Python, applying regex-based data preprocessing and string normalization techniques to handle alias variation and cross-language inconsistencies.• Collected and cleaned approximately name records from internal onboarding systems and public sanction lists using Pandas and NumPy, ensuring data integrity through standard transformation techniques like lowercasing, punctuation removal, and whitespace normalization.• Engineered similarity features using TF-IDF (Scikit-learn) and Levenshtein distance and implemented phonetic encoding using basic supervised learning concepts to support fuzzy and partial match logic across multilingual name inputs.• Developed and tested a simple matching model using Scikit-learn and K-Nearest Neighbors (KNN), helping improve match classification accuracy from 70% to 82% during the testing phase through threshold tuning and iterative feedback from compliance analysts.• Evaluated model outputs using Accuracy, Precision, Recall, and F1-Score, visualized results using Matplotlib andSeaborn, and contributed to a 10–12% reduction in false positives, easing review workloads for the AML operations team.•Supported automation of periodic name screening by developing a lightweight ETL script in Python, integrated with a MySQL backend, enabling re-screening of around 1,500 customer records on a biweekly basis as part of compliance review processes.•Collaborated with senior data scientists and compliance stakeholders to document logic, validate screening outcomes, and apply Hypothesis Testing, Statistical Modeling, and Data Quality Assurance principles in an Agile Development setup.
