Summary
👤
Senior🎓
Top SchoolEric Choi is a Staff Software Engineer with 11 years of experience building high-throughput, backend systems for email and large-scale web platforms, currently at Twilio after SendGrid's acquisition. He specializes in Go and Perl and has deep operational experience with Kafka, Ceph, Kubernetes, AWS, and containerized infrastructure that powers billions of daily emails and tens of billions of events. At SendGrid he designed core platform pieces—from an AWS-backed API gateway with JWT auth to a hierarchical distributed scheduler (pending patent) and syslog/Kafka logging pipelines—demonstrating both systems design and production-grade engineering. Earlier roles at Ticketmaster and other companies show a strong foundation in Perl-based web stacks and service-oriented API design for checkout and payment flows. Based in Brea, California, Eric combines academic rigor (BS and MS in CS/Math & Physics) with pragmatic tooling choices, often bridging legacy architectures and modern cloud-native practices. He’s the kind of engineer who architects for scale while still shipping low-level parsers and logging libraries that keep the platform observable and reliable.
