About Dennis Mullen

I am a web developer for Knox County (Tennessee) government, working on the web pages and apps that connect the people of Knox County to their government and services. I use the JavaScript framework Vue, Amazon Web Services (including Lambda, API Gateway, Cognito, Elastic Beanstalk, Simple Email Service, etc.) to build apps that interact with SQL and DynamoDB databases. I also help maintain legacy code written in PHP, and develop WordPress sites.I worked previously as a web development specialist on the User Interface (UI) team at iXsystems in Maryville Tennessee. We built the UI for FreeNAS (now TrueNAS), the great open source operating system for Network Attached Storage. I used HTML, CSS, TypeScript and JavaScript and Angular, the TypeScript-based web framework, to help build a beautiful and practical user interface which interacts with the operating system.My long-term experience as a pastor includes teaching, leading teams of staff and volunteers, managing a budget, casting vision, facilities management and information technology work. I love working with people and with technology, and am most pleased when the two of these meet.

Listed skills include Javascript, Html5, Css, Jquery, and 12 others.
