About

I'm Josh Haller. I graduated from Leeds in 2026. I spent four months on Trafigura's coal desk in Barranquilla doing cargo operations. Nothing on this site comes from that work: the data and errors are invented. I built this while applying for junior operations roles myself. Every application tests Excel, and more of them now test SQL, but the work behind those tests is reconciliation and laytime arithmetic, and nobody teaches it. There are courses on incoterms and tutorials on SQL, and nothing in between.

Counterparties, vessels, voyages and invoices are invented. Ports and grades are real. Not affiliated with any trading firm.
