Rockstar🎓
Top SchoolOphir Lojkine is a pragmatic CTO and senior software engineer with 14 years of experience building data-intensive and real-time systems for energy markets and cloud services, currently leading engineering and technical strategy at Enexflow/Zetra from Paris. He combines deep systems and backend expertise—demonstrated by contributions to high-profile Rust and tooling projects like image-rs, broot, ReadySet and emscripten—with hands-on product work on front-end experiences such as react-contenteditable and collaborative Whiteboard. At Enexflow he architects large-scale platforms for virtual power plants, automated optimization and market integrations handling gigawatts of assets and sub-second data flows. Comfortable across the stack, he moves between Rust, Python and JS, with a track record of improving performance, robustness and security in open-source protocol and compiler tooling. Trained in France and Russia (Centrale Nantes, Bauman MSTU), he pairs formal engineering background with a hacker’s curiosity, often surfacing subtle bug fixes like integer-overflow and streaming-aware encoders. Colleagues describe him as a refactor-first engineer who elevates error handling and developer ergonomics while scaling production systems.
