Top SchoolZbynek Stara is a Senior JavaScript Developer based in Prague with 11 years of professional experience and seven years focused on full-stack JavaScript, TypeScript, and SVG-heavy front-end work. He has led and mentored agile teams of up to six junior developers while delivering complex integrations for multinational clients, from ServiceNow ITSM/ITOM APIs to data visualization and mobile features. At client IO he helped steer product direction for the JointJS diagramming library, driving its transition to a monorepo and contributing algorithmic improvements (e.g., convex hull, Bézier and pathfinding enhancements) that improved layout and labeling usability. His background includes data-driven analysis at Google and a knack for clear technical writing and marketing—authoring tutorials and comparative pieces that demystify competing diagramming tools. Comfortable bridging product, engineering, and client-facing roles, he combines hands-on geometry and visualization engineering with pragmatic leadership and documentation skills.
