Post-Yammer acquisition position. Member of the Infrastructure team responsible for accelerating the rest of engineering. Responsible for multiple open-source initiatives around trying to make large distributed systems more resilient.

Post-Yammer acquisition position. Managed the Infrastructure Services/Tools team which focused on empowering development. Designed and implemented a social peer-access host-based authorizing service. Evangelized the use of a resiliency library focused on service dependencies. Implemented a service to provide real-time metrics of services dependencies and real-time configuration.

Designed and implemented services to aid in the development of services. Projects include the deployment system for everything behind Yammer.com (50+ services). A measurement, real-time analytics, and vertical profiling system for the main Ruby/Rails application (broken down by controller/action/block). A machine provisioning system which makes use of raw Juniper switches, raw machines, and allows for one-click provisioning.

• A major designer and developer on an internal scalable, fault-tolerant, distributed, and high available object storage system (storage.adobe.com ~4PB) [C++, Python]• Core designer and developer of an algorithm to handle node failures. Aimed to quickly restore any lost objects without any loss of data. Improved recovery times by several magnitudes.• Added functionality to take improve internal processes that could be parallelized. Reduced completion times by several magnitudes.• Added the ability for the system to support live migration of objects while users were modifying the data.• Solo effort to write a incident response system that monitors, alerting (SMS/e-mail), graphs, and auto stabilizes object storage clusters. All design, implementation, and testing was solo. It also allows for advanced monitoring techniques (e.g. rate-of-change, graph comparison, multi-datacenter, horizontal, and vertical scaling). [Java, Scala, Lift]

•Developed a feature for QuickBooks that automated a task for the user which was previously a tedious manual operation. [C++]•Conducted usability research with actual live customers to satisfy user requests and to reduce technical support calls.•Initiated and developed a white box testing (WBT) project to target the legacy code of QuickBooks. Presented the WBT to my manager and director who have continued my work.•Volunteered to engineer a direct deposit feature by a deadline that was very optimistic. Completed the feature on time and with all functionality working.
