A legacy web application that provides a control panel for the different hosting and cloud products that Rackspace provides. The project is focused toward maintaining and improving the web application and accommodating the changes required by the new features and products Rackspace provides.

Half Price Books

Developed the eCommerce platform for a major used bookstore with a team of ten, supporting over 8 million products, marketplace, and stock integration.

Sayish

Team collaboration tool directed to web development. The tool included a chrome extension (React) that allowed the user to annotate web pages, live or locally, and share the notes within a project/team.

The front end was React and the back-end was fully Node.js, including a system to receive inbound emails to collaborate.

Measured Progress

Worked as a developer and consultant in a project to migrate a web application to support the creation of K-12 tests and assessments.

The project was heavily based on the client side, using JavaScript and a set of tools to allow editing texts and media. The back end was C# MVC 2 and NHibernate for persistance—something compared to a text processor like OpenOffice Writer.

Technology/Tools: JavaScript, C#, Java, HTML, CSS, NHibernate, Web Driver, Git-SVN, MS SQL and JBehave.
