At Shipwell, I build Python services that match carrier invoices to shipment records and booked charges, flag discrepancies for review, and send reconciliation results to customer accounting systems. I also built an LLM agent pilot for invoice exceptions, with tool-based evidence gathering, replay evaluation, and human review before case creation.
At Chargify / Maxio, I built recurring billing workflows for B2B SaaS customers. I reworked renewals into independently retryable jobs and added safeguards so retries produce one invoice per renewal.
At Visa, I built Java services and SQL reports to reconcile card clearing totals against settlement amounts. I also fixed late-file reconciliation to use the original processing date.
Earlier, at uShip, I built carrier feed adapters and maintained shipment tracking; at The University of Texas at Austin, I worked on GPS-based trip reconstruction and travel-time estimation. I hold M.S. and B.S. degrees in Computer Science from The University of Texas at Austin.
