What are some of the types of development projects you have worked on in your past positions?

"In my last two roles, I was focused on improving applications which manage transactions and interact with relational database systems. My role in the application development was developing all the code to control data queries, lookups, and indexing of the data. I worked with other programmers to design the interface, manage the backend database, and develop other application features. The companies I worked for were focused on e-commerce, conducting sales and other transactions via their websites."
