Summary
👤
Senior🎓
Top SchoolRyan Perry-nguyen is a Developer Tools Engineer with 11 years of experience building and scaling backend systems, primarily at Wealthsimple, where he transformed critical accounting services to be faster, leaner, and more autonomous. He specializes in domain-driven design, hexagonal architectures, and event-driven, stream-based computation—having cut SQL calls dramatically, reduced endpoint latency to ~100–200ms, and converted manual finance processes into automated, auditable pipelines. Comfortable across the stack, he has led front-end overhauls, engineered coordinated test-data systems for microservice staging, and applied profiling/tracing to reduce memory use in production. Based in Old Toronto, he brings a data-driven, patient approach to problem solving and a knack for turning legacy polling systems into distributed map-reduce architectures that reliably power business-critical metrics.
