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.

I also supported the business analysts to identify, define, and analyze these features. As a part of a distributed agile team, I regularly collaborated with business stakeholders, analysts, testers, and other developers.
