I worked on the Dataswarm infrastructure team and my project was parallelizing a process that compiled task dependencies from workflow files. I started by first collecting metrics on the process to determine that parallelizing the process would be successful and what the expected speedup would be. When that was successful, I found a way to partition the workflow files across the clusters of machines and aggregate the output. In addition, I added error checking logic for each child process. Eventually, I brought the runtime down by 65% and allowed for future horizontal scaling.

I interned on the Kindle Fire Tablet team and worked on caching for the storefront page. I enabled caching so that reloading the page within a cache's expire time would automatically load from the cache. In addition, I designed a custom Etag for validation so that if the page had not changed even after the cache expired, it could be loaded from the cache. In addition, I generalized the caching technique with aspect oriented programming architecture so that it could be used for other pages.

As a quality assurance engineer intern, I mainly developed automated JUnit scripts for phones and tablets to reduce manual testing. These scripts checked the UI/UX of the applications and ensured the mobile app was receiving and displaying the correct JSON objects from servers. In addition, I executed longevity/reliability testing of a media dongle through automated testing and manually tested the general functionality of media dongle (connectivity, pairing, streaming).
