Kyle Krupp is a Principal Software Engineer based in Grand Rapids with eight years of experience building cloud-native, event-driven systems and modern web experiences. At Liberty Mutual he leads GraphQL federation and schema governance while maintaining Supergraph artifacts like the Apollo Router and coprocessors to accelerate federated API delivery. He combines hands-on full‑stack work — Single SPA + React MFEs, Node.js/TypeScript services, and AWS serverless ETL — with cross-team coordination between business stakeholders and third‑party vendors. Kyle has a track record of replacing monolithic sagas with event-driven Step Functions architectures and driving TypeScript and IaC adoption across teams. Beyond day-to-day delivery he focuses on platform-level middleware and governance to make developer velocity repeatable and secure. His background in data visualization and product-facing roles gives him a practical sense for translating UX needs into scalable backend solutions.
