At Null Labs, I own the data platform behind Argus, a Walmart deduction-recovery product, from supplier data ingestion through a six-layer PostgreSQL warehouse and reporting. I automated daily invoice, payment, and deduction collection, and built traceability so each short payment links back to its invoice.
I designed a versioned rules knowledge base that classifies deductions by root cause and dispute value, and built Python pipelines with validation, quarantine, and safe incremental loads. I’m building a RAG assistant that explains deductions using Walmart’s rules and supplier contracts, alongside agents that draft disputes for a person to approve.
At Bosch Car Service, I automated monthly reporting, reducing its cycle from three days to under two hours, and designed a star schema for inventory, procurement, and finance KPIs. My projects include Airflow data pipelines, PostgreSQL warehouses, and validated local LLM summaries.
