Joey Ballentine is a Software Engineer III with eight years of hands-on experience building backend systems, developer tooling, and polished front-end experiences from Milwaukee. Currently the main backend developer for Sharpen’s Logic+ no-code automation and IVR flow builder, he works across Node.js/TypeScript, Redis, SQL/MongoDB, and AWS CDK while also contributing React front-end code. An active open-source contributor, Joey has shipped memory-reading game integrations and UI improvements for Aurora, built backend APIs and node factories for the chaiNNer image-processing project, and implemented custom edge rendering for React/Svelte Flow libraries. He brings a practical mix of legacy system maintenance and modern cloud-native engineering, plus a knack for bridging low-level integrations (memory reading, IVR tooling) with user-friendly interfaces. Joey holds a Computer Software Engineering degree from the University of Nebraska–Lincoln and regularly improves code quality through linting, testing, and thoughtful API design.
