Backend Software Engineer at GlobalSign
Asturias, United Kingdom
Summary
🤩
RockstarDom Dwyer is a backend software engineer with 11 years of experience building robust, production-grade services and drivers. Currently at GlobalSign and formerly at InfluxData and StorageOS, he specializes in concurrency-safe systems and dependency resilience for cloud-native infrastructure. An active open-source contributor, Dom strengthened the Go AMQP client by fixing race conditions and adding TLS support, and improved MongoDB and RoaringBitmap libraries with dependency fixes, performance tuning, and thorough tests and benchmarks. He leans toward low-level reliability work—connection management, thread-safe shutdowns, and efficient bitset operations—bringing a meticulous, test-first mentality to complex distributed problems. Based in Asturias (UK), he combines hands-on coding with a pragmatic focus on preventing subtle concurrency bugs that often surface only in scale.
