Over three months, contributed to the BA-DCS-lastsemmaxxing repository by building an end-to-end pipeline for regulatory and financial text analytics, focusing on automated OCR-based PDF processing, robust text extraction, and scalable classification workflows. Leveraged Python, Jupyter Notebooks, and AWS Bedrock to implement preprocessing, hybrid sample-based and rule-based classifiers, and retraining pipelines informed by user feedback. Enhanced data quality through advanced EDA, stopword removal, and hybrid sampling, while integrating explainability with LIME for model transparency. Maintained clear documentation and repository hygiene, supporting efficient onboarding and collaboration. The work emphasized maintainability, modularity, and business-aligned data processing for document classification tasks.
March 2025 monthly summary for BA_DCS_lastsemmaxxing project focused on delivering a robust, business-enabled classification and topic-processing pipeline, with integrated retraining and explainability workflows.

February 2025 monthly summary for BA_DCS_lastsemmaxxing: Delivered a set of core text processing, classification, and repository hygiene enhancements that collectively improve data quality, model efficiency, and maintainability, translating to clearer business value and faster iteration cycles. Key focus areas included robust preprocessing with stopword removal, advanced exploratory data analysis (EDA) to inform sampling and feature engineering, a rule-based classifier to provide a lightweight, explainable baseline, and a hybrid sampling approach to reduce processing load while preserving signal. Complementary documentation and hygiene improvements enhanced onboarding and collaboration. Impact highlights: Improved preprocessing quality and consistency with NLTK stopwords, more efficient and targeted model inputs via hybrid sampling, an extensible rule-based baseline for quick iteration and interpretability, and improved repository clarity (README with Figma wireframe, .gitignore hygiene) that reduces onboarding time and release risk.
