Summary
🤩
Rockstar🎓
Top SchoolVitali Lovich is a Principal Software Engineer with 14+ years of experience building systems that scale—from low-level firmware and window managers to large-scale cloud storage and high-throughput backends. He led Cloudflare’s R2 from 0 to exabyte-scale and rearchitected Workers KV to cut operational costs by ~90%, and his work has run on billions of iOS devices and hundreds of millions of TVs. Equally at home in product and UX conversations, he catalyzes cross-functional teams to unblock hard problems (e.g., driving Oculus Link out of beta and enabling USB2 support to recover 20% of users). A pragmatic systems thinker and hands-on coder, he contributes to notable open-source projects like Cloudflare’s workerd and Cap’n Proto, improving KV semantics and I/O performance. Recently pivoting into AI and aviation work, he also founded a startup building a high-performance KV store, demonstrating both technical depth and entrepreneurial risk-taking.
