Jaroslav Snajdr is a seasoned JavaScript engineer with over two decades of experience building scalable collaboration and email server software, now contributing to Automattic. Trained as a mathematician, he learned programming from Knuth and early systems work, evolving from C++ systems and embedded Firebird tuning to leading full-stack Java and modern JavaScript product teams. He led the creation and scaling of Kerio Connect and Kerio Workspace—systems still running at major portals—and later guided Samepage's core product before moving into frontend engineering at Automattic. His open-source contributions include build and front-end improvements to high-profile WordPress projects like Calypso, Gutenberg and Jetpack, with practical expertise in bundling, transpilation, and modern JS tooling for Electron. Colleagues rely on him for pragmatic architecture, performance-minded engineering, and a rare combination of low-level systems instincts with polished UX-focused frontend craft.
