Summary

Led the design, development, and deployment of an ocean-freight surcharge platform and LLM-powered data extraction layers for global carriers, enhancing data processing efficiency and accuracy.

Highlights

Designed and shipped an ocean-freight surcharge platform, processing tariff rule books from 13 global carriers (MSC, CMA CGM, Hapag-Lloyd, etc.) into a normalized, database-ready schema for PostgreSQL and Google Sheets.

Developed Python scrapers using REST/JSON APIs and headless browsers, reducing manual tariff review time from days to an automated scheduled job with nobody watching it.

Engineered an LLM extraction layer (Gemini, Claude on Vertex AI) with strict output schemas, achieving 0 misses across 700+ Hapag-Lloyd rules and 15 PDF tariffs.

Built a comprehensive location layer for UN/LOCODE resolution, trade-lane classification, and port/terminal name clean-up, improving quality reports from 7 failures to 0 before customer demo.

Packaged the entire system into a single Docker image with Cloud Run deployment per carrier, delivering 50+ reviewed pull requests on GitHub with verified output diffs.
