In my current job, I am working on testing and automated deployment of software-as-a-service (SaaS) programs. In my previous job, I was working with Docker, AWS, and Jenkins to implement a testing and continuous integration framework for our web application. In my gig before that, I helped develop a dynamically generated web site, its Python back end REST interface, and maintained a LAMP (Linux, Apache, MySQL, PHP) web site. Details are in my résumé.
I have done a number of open source projects over the years, and use a lot of open source in my work, but my focus now is on professional software development.
