Rockstar🎓
Top SchoolGeorge Asfour is a backend engineer with nine years’ experience building and optimizing high‑traffic Ruby on Rails and Go services from Osaka, Japan. He has driven performance improvements, developer experience upgrades, and enterprise integrations—most recently implementing LLM integrations and multi‑processor payment flows at Evil Martians. A strong focus on testability and code quality is evident from his open‑source contributions to the ActionPolicy authorization framework, where he refactored core logic and added RSpec matchers.

Comfortable operating across the full stack of infrastructure, APIs, and k8s clusters, he combines hands‑on debugging (profiling, memory and performance tooling) with delivering production features. He’s driven by continuous learning and seeks projects that meaningfully impact users and systems.
