  • At Karr Barth Administrators I was brought on to support the three-person team of software developers. I was able to take the leadership on many projects which I conceived, designed, developed, tested, published, and maintained. I brought many modern ideas and workflows to the team. We were able to streamline our development process and after losing a member of our three person team we were able to continue without a new hire due to my ability to get work done correctly and in a timely matter.
  • As a junior developer, I had assumed the role of a senior developer on my team at Computer Aid Inc. I have made many key design and architectural decisions. I was often the go-to person to answer technical questions on our team, even when I only had two years of experience. I led our team to many design decisions that have saved countless hours in coding time.


  • For my college senior project I wrote an Eclipse IDE plugin and wrote a paper that was published by ACM. The plugin for the used Java to create real-time collaborative coding environment built on the Google Wave protocol. I designed and developed the project by utilizing APIs from various sources and experimented with emerging open source technologies. Our paper was published by ACM and the project was presented at the 2010 SIGITE conference. The paper is available at and the code source is available at
