•Led project to create a resource monitor for our application. The monitor used queries to the YARN Resource Manager as well as Mongo and Redis databases to provide information about resource consumption, user activity, and license limits. It helped admins debug issues in production and see which users are consuming the most resources.
•Led internal security audit of our public API. Added code to ensure requests to existing routes matched expected input. Also added code to force new routes to validate input requests before they accessed the data it contained.
•Added ability to download, modify, and upload generalized additive models to the Python API client.
•Added indexes to mongo tables to speed up performance of some queries.
•Participate in rotating firefighter role, on-call position to debug issues in production systems.
•Use Agile development practices daily.
