Romain Sylvian is a Staff Software Engineer with 14 years of experience specializing in front-end architecture and developer-facing platforms. He’s led teams of up to 11 engineers to build high-traffic documentation and developer hubs (millions of annual visits) and has launched products from scratch, including a Figma-centered collaboration tool that was later acquired by Adobe. Comfortable across the full JavaScript stack, he has shipped performance optimizations (e.g., 30% faster sync for a desktop client), cross-platform Electron/Windows support, and scalable cloud APIs. Romain blends hands-on coding with engineering leadership—regular one-on-ones, code reviews, and career coaching are core to his management style. Based in Laguna Niguel, he pairs a formal CS education with startup and product experience that spans freelance ventures sold to larger buyers. A pragmatic problem-solver, he focuses on developer experience and measurable performance gains rather than flashy tech for its own sake.
