Systems Under Pressure
Schonfeld Securities / Tradeweb
Low-latency markets, legacy code, and the habit of leaving things better.
Before the founder years, I learned how to make progress inside systems that were already moving.
Low-latency trading, legacy refactors, production health checks, release trains, undocumented components - not glamorous work, but the kind that teaches respect for reality.
The pattern stuck: understand the system, find the leverage point, make the next change easier for the next person.
