Senior🎓
Top SchoolZac Butko is a Senior Frontend Engineer based in Sunnyvale with seven years of experience building user-focused web applications and shipping production React/TypeScript systems. He has scaled from founding a SaaS (MM-SEAS) to improving healthcare EMR UIs as a core contributor to OpenMRS front-end modules, where his timeline and Results Viewer refactors improved clinical data presentation. At NVIDIA and prior roles he blends front-end craftsmanship with full-stack sensibilities, solid product instincts, and a history of stabilizing navigation and error-handling across large apps. His background in applied physics and past work in data-driven roles at Mercedes-Benz inform a methodical, metrics-minded approach to UX and performance. Colleagues value him for turning messy requirements into polished, testable interfaces and for keeping documentation and repo hygiene up to date—small habits that prevent large outages.
