Nelson Joseph has been building software on Wall Street since before the dot-com bubble, close enough to the trading desk to know that “urgent” has several distinct meanings, none of which include tomorrow.
His specialty is OTC products and derivatives: turning complex trades into pricing tools, risk analytics and workflows that hold up when the market stops being cooperative. He typically works with one or two traders at a time, and the job depends as much on knowing how they actually operate as on knowing the product.
He was in the building when Bear Stearns unraveled. The experience permanently shaped his views on counterparty risk, job security, and keeping his résumé somewhere other than his work computer.
His posts here are short and come from the desk: identifiers mangled by spreadsheets, money stored in floating point, dashboards that call yesterday’s positions live, and reports that recompute a day’s trading every morning. The common thread is that most of these problems are fixed by ownership and arithmetic, not by a new platform.
