* Designed, built, and supported software for personalization and data processing.* Implemented continuous integration for all team's projects, surfacing integration issues days earlier than prior.* Automated releases for all of team's projects reducing time to make releases from 30 minutes to less than a minute.* Improved software resiliency resulting in an approximate 25% increase in productivity.* Increased organizational flexibility by simplifying team’s software support needs to no longer require a domain expert.* Improved reliability of refactoring and adding new features by working with team to consistently unit test code.

* Led development for numerous projects throughout their entire lifecycle.* Created successful strategy for integrating with 3rd parties, including verbose audit trails to improve integration diagnostics.* Increased software resiliency freeing key developers from support obligations.* Automated deploys reducing time spent on them from 2 day affairs to 15 minutes.* Automated releases eliminating inconsistencies in how releases were made (versions not tagged, JARs with code not in repository, etc.).* Facilitated transition from Java to Groovy reducing average code size by roughly 2/3rds.* Proposed and developed a solution to meet the requirements of a project that was significantly constrained in budget due to a contractual oversight.* Worked with leadership to ensure team cohesion and consistency, which led to improved productivity and efficiency.
