Carolinemodic

Caroline Modic engineered robust election technology features in the votingworks/vxsuite repository, focusing on secure QR-based reporting, multi-precinct pollbook workflows, and data integrity for voter management. She designed and implemented backend APIs and frontend React components using TypeScript and Node.js, enabling precinct-aware exports, ballot rotation, and real-time reporting with QR code generation and signature verification. Caroline’s work included database migrations, test automation, and networked system safeguards to prevent misconfiguration and ensure compliance. By integrating caching, error handling, and observability, she delivered reliable, scalable solutions that improved operational efficiency, auditability, and user experience across complex, distributed election environments.
