Santiago Gutierrez

At PampaDirect, I’m the sole backend engineer supporting five e-commerce brands across Argentina, Uruguay, Brazil, and the US. I build production systems end to end, from schema design and third-party integrations to deployment, monitoring, and on-call ownership.

I automated carrier invoice auditing across 70,000+ FedEx shipments and $2.6M in invoices, recovering approximately $110K while moving claims before payment. I also run FedEx, UPS, and DHL integrations behind a unified request schema and keep PostgreSQL synchronized with BigCommerce, Amazon, and CS-Cart.

Previously at Tenaris, I built Python and Azure logistics automation, co-developed an offline field inventory app, and improved the company-wide password self-service tool. I worked through sprint planning, separate development, testing, and production environments, and release reviews.

I also ship practical products independently, including a live Go, PostgreSQL, and React management system for an electronics repair shop. My work focuses on making operational processes measurable, reliable, and easier to run.
