Want to get into details as to what kind of "snazzy technology" or "amazing code" you guys are involved in? You don't have to give me corporate espionage secrets, just vague general topic. Is it a flashy OMS/EMS/reporting/risk/quotes front-end? What kind of technical problems do you guys encounter? In terms of concurrency, security, message processing, bandwidth/latency? What kind of business problems do you guys encounter? In terms of smart-routing, risk calculations and compliance. Just curious what programmers in GS are generally involved in.
