Summary
👤
SeniorGreg Retkowski is a seasoned infrastructure and DevOps leader with 16+ years of experience building and scaling cloud, automation, and monitoring platforms across startups and large enterprises. As President of Raging Network Services and a former principal engineer and team lead at Upwork, he has launched high-impact initiatives—synthetic monitoring, anomaly detection, and real user monitoring—that materially doubled incident detection within tight SLO windows. Greg combines hands-on implementation (OpenStack pilots, GitLab migrations, logging systems handling petabytes, and on‑prem LLM deployments) with team-building and TPM responsibilities, consistently delivering projects on time and on budget. He’s known for rescuing and rearchitecting critical production systems (e.g., logging pipelines scaled 4x and retention/query capability improved 26x) while instilling CI, testing, and release discipline. Comfortable in both startup scrappiness and enterprise governance, he pairs deep systems knowledge with a knack for turning operational messes into observable, automated platforms. Based in San Diego, he steadily mentors engineers into top performers and still writes integration tooling when the problem demands it.
