* Productized and operated machine learning systems at scale to serve recommendations to millions of users* Created a configuration system that drastically reduced the time required to stand up an A/B test, enabled near-instant rollback, combined compatible tests in a declarative manner, and protected against conflicts* Wrote and refactored continuous integration (CI) pipelines to increase development velocity and improve confidence in changes* Ran numerous A/B Tests that moved core business metrics. Responsible for test implementation, compute performance, cost analysis, validation, and monitoring. Worked cross-functionally to drive the tests* Found and fixed performance issues in order to maintain SLA (kept service latency under a pre-determined threshold), reduce cloud costs, and improve stability

Service Deployment Platform* Worked with another engineer to build an etcd-backed system for configuring and managing services* Designed and implemented: HTTP API, service discovery, storage schema, migration framework, configuration validation, and transaction protocol allowing the composition of arbitrary HTTP calls into an atomic commit* Created a system for securely managing secrets, relying on TLS certificates for authentication* Redesigned the remote agent to overcome race conditions; the new design centers on a state machine with tight control of I/O and limited parallelism. Asynchronous operation is enabled through full linearization of the input

Data Integration Infrastructure* Worked with a small team to build infrastructure for creating and maintaining data pipelines composed of jobs (e.g. MapReduce, Python, Spark) and heterogeneous datasets* Designed and implemented a distributed coordinator responsible for synchronizing and executing long-running tasks across dependency graphs of transformations and data* Responsible for HTTP API, transaction protocol, index, Hadoop and S3 interfaces* Mentored an intern and conducted interviews, both over the phone and in-person

* Developed an algorithm to identify coherent events in seismic data using image processing techniques* Implemented this algorithm along with user-facing controls as a plugin for a proprietary software platform
