Top SchoolJon Rohan is a Staff Software Engineer based in Seattle with nearly two decades of experience specializing in front-end engineering and design. At GitHub he helped scale the platform from hundreds of thousands to tens of millions of users, led the creation and evolution of Primer and Octicons, and refactored UI into reusable design-system components used across the product. Comfortable across CSS, JS/React, Ruby/Rails and build tooling, he blends product-facing design sensibilities with hands-on engineering—shipping everything from Atom editor UI tweaks to scalable React components. He’s repeatedly focused on performance, usability and developer ergonomics, and has a track record of improving tooling and build systems (including migrating icon workflows from fonts to SVGs). Known for thoughtful front-end craftsmanship, he also contributes backend improvements where needed, such as enhancing HTML processing and SVG generation.
