Kevin Zeillmann is a product-focused full-stack engineer with 11 years of experience building reliable, user-centered web platforms and developer tooling. Currently a Senior Engineer II at Kajabi, he drives commerce features for creators while pioneering engineering improvements—most notably leading a company-wide migration from Webpack to Vite that cut local development cycle time by over 20x and introducing the first production TypeScript in the codebase. His background spans end-to-end system ownership from AWS infrastructure and Kotlin microservices to Next.js front-ends, and he has a track record of improving CI/CD, performance, and developer productivity at scale. Comfortable mentoring and operating in on-call rotations, he pairs a mathematician’s rigor (Vanderbilt degree) with pragmatic product sensibilities and a knack for turning complex legacy systems into maintainable platforms.
