As a senior software engineer at Ensenda, a third party logistics company, I developed and designed the core business model and application code that enables the deliveries of some of the biggest retail companies in the country. Because I was a member of a small, constantly changing IT organization, I had opportunities to work within small teams, lead a small team, and be responsible for several projects on my own. An aggressive pipeline of new features and customers allowed me to both exercise my experience in areas outside of software engineering, such as database and system administration, and let me pick up and apply new skills along the way.

Developed the Perl business objects, DB Schema, and services/APIs
Responsible for and directed the in-house business reporting solutions
Implemented performance metrics and analysis
Guided release and build management
Constructed a working prototype of a Java Hibernate persistence layer to replace an existing in-house Perl ORM using Inline::Java, while still keeping the Perl view and service layer intact
Developed an Adaptive Object Model (AOM) framework that allowed the domain model to be customizable by the business to better serve each customer's needs
