Applied AI & Machine Learning

Leakage-safe financial complaint-routing architecture showing parallel TF-IDF and DistilBERT model paths, shared 2024 evaluation, model-specific routing, auto-route recommendations, and human review.

NLP CLASSIFICATION / SELECTIVE ROUTING

COMPLETED V1–V2 STUDY

Financial Complaint Auto-Routing with NLP

Leakage-safe eight-class CFPB complaint-routing study comparing a locked TF-IDF + Linear SVM benchmark with a frozen DistilBERT challenger, using development-selected routing policies and retrospective 2025 evaluation.

Corrected duplicate-text leakage and created group-aware 2024 development and final-test partitions with zero normalized-text overlap.
Compared the locked TF-IDF + Linear SVM benchmark with the frozen DistilBERT challenger; Macro F1 on the shared 2024 benchmark improved from 0.7671 to 0.7949.

About

I’m a Data & AI Engineer focused on building reliable cloud data platforms and applied AI systems. I work across API ingestion, cloud storage, transformation, data quality, analytics, and ML/RAG workflows using Python, SQL, Azure, AWS, Databricks, and PostgreSQL.

I value reproducible workflows, clear evaluation, maintainable code, and documentation that makes technical decisions easy to review. My background in analytics and web development helps me connect backend data systems with reporting needs and polished user-facing applications.
