Top SchoolJeffrey Parker is a versatile software engineer with 14 years of experience building mobile apps, back-end APIs, and front-end websites from Ann Arbor, Michigan. He has shipped production Android and Windows UWP clients and led architectural and testing improvements at Expedia Group before moving to Duo Security. Comfortable across Kotlin, Python, C#, Java and JavaScript, he pairs hands-on coding with systems thinking—setting up CI/CD pipelines, automated analysis, and end-to-end release systems. His background includes full-stack projects combining AngularJS, Python REST APIs, DynamoDB, and websocket-driven live views, plus operational experience migrating services to AWS.
