Summary

Rockstar🎓
Top SchoolAlexander B is a seasoned software engineer with 11 years of experience building and operating large-scale infrastructure and backend systems, currently driving config management and cost-optimization efforts at Pinterest. He’s delivered dramatic operational wins—cutting deployment p90 times from 19 to 2 minutes and implementing EC2 provisioning controls that saved roughly $22M/year—while working across Golang, Protobuf/GRPC, Bazel, and data stacks. His background spans low-level systems and SRE roles at Jane Street and Facebook, where he managed thousands of production hosts, created a CDN to shrink build times, and rescued idle hardware into service. An active contributor to the high-profile nats-server project, he’s comfortable modifying core messaging server behavior and improving tests and build constraints. Alex combines production-first engineering with a strong automation and tooling mindset, and he has an uncommon mix of trading-infrastructure experience and cloud cost engineering.
