Jevin Nishioka

SWE at Deloitte. I embed with enterprise clients and build distributed backend systems.

At a defense contractor, I'm building an event source spine linking factory-floor systems to enterprise ERP, along with an LLM-powered sync job keeping scattered internal specifications consistent.

Previously, I built high-availability, user-facing services for a Fortune 50 brokerage.
