Senior Software Engineer Team Lead

• Designed, developed, deployed and performed ongoing maintenance for a Shopping Cart
Abandonment service allowing our clients to gain valuable insights into their customers' shopping habits. The SCA service is a Java service built using REST best practices, Jackson, Jersey, Spring, and Hibernate with a MySQL and HBase backend.
• Implemented multiple client-facing features in both PHP and Java to allow our online retail clients to gain valuable insight into their email, mobile, and social marketing campaigns.
• Wrote backend Java code to capture, aggregate and report on email tracking statistics, which has to support a scale of 60+ million email deliveries and hundreds of millions of tracking events daily.
• Designed, implemented and maintained the development of an automated messaging system which gives our clients the ability to automatically send email deliveries based on contact actions and date based triggers without any user interaction.
• Implemented and tested key infrastructure changes that were necessary to move our application from using a Cassandra data warehousing backend to HBase.
• Helped migrate hundreds of millions of message, delivery and delivery group objects and statistics from Cassandra to HBase, which required the development of many custom Java jobs to ensure accurate results with minimal application downtime and obstruction to client workflows.
