Summary

Senior🎓
Top SchoolOlek Poplavsky is a Senior Lead Principal Software Engineer with 18 years of experience building high-performance, highly scalable systems across Rails, Java and Clojure. At Salesforce he turned prototypes into production-grade services that fetch hundreds of gigabytes of email daily and rewrote high-throughput APIs to deliver 5x better latency with a fraction of the infrastructure. He has led end-to-end platform rewrites, mentored teams, and championed quality-driven engineering practices that keep delivery velocity high. Earlier roles span eCommerce, media delivery, and biosurveillance, giving him deep practical experience in optimization, provisioning, and operational reliability. An advocate for pragmatic, maintainable code, he also contributes focused open-source improvements—like optimizing Redis-backed Rails session handling to avoid unnecessary writes. His approach to craftsmanship in software is informed as much by system-level performance tradeoffs as by a philosophical attention to quality.
