Summary
🤩
Rockstar🎓
Top SchoolAhmad Sherif is a Production Engineer based in Amsterdam with 13 years of experience building and optimizing large Ruby-on-Rails systems and cloud-native infrastructure. At GitLab he focuses on performance tuning, monitoring, on-call incident response, and critical migrations including moving SaaS to GCP and migrating PostgreSQL to Patroni. He pairs deep Ruby expertise—evident from substantial test and core-library work in ruby/spec and contributions to Rubinius—with hands-on DevOps skills from managing Omnibus, Gitaly and configuration for Consul and Patroni. Comfortable across backend code, infrastructure as code and load testing, he has a track record of shipping reliable production services and improving core language behavior and runtime correctness. An interesting detail: he contributes to language-level specs for Ruby while simultaneously running production-grade monitoring and platform migrations, bridging low-level correctness with large-scale operational engineering.
