All things engineering! Wide array of integration efforts with healthcare Electronic Medical Record Systems such as Athena, Epic, Meditech, and Cerner.

Cloud Migration – Lead for a complete migration from AWS infrastructure for two data product business lines to Google Cloud Platform (GCP) for all of Netwise Data and Platform teams. Two disparate architectures were unified into one architecture with separate implementations of the same ETL execution framework. This resulted in simplicity and uniformity and eliminated the need to deeply understand dead code and architecture. BQM2 - BigQuery Materializer 2 (open sourced), detailed in ShareThis experience, was leveraged to orchestrate the loading, transformation, and export of all data products and two multi-million dollar business lines.

Data Quality and Scale Control and Monitoring Framework - created a comprehensive and highly customizable data quality assertion framework for the migrations. The framework allows for the insertion of quality and scale gates at any stage.

Developed N-Way Unique Contribution analysis framework - applied this framework to a variety of use cases across Netwise, Audience Targeting, and Eyeota use cases. N-Way provides easy answers to the often asked questions - What does or will this data source uniquely contribute to our data offering and or business? Where does the source agree with other sources? What’s the overlap and with who?

Highly Expressive but Simple CI/CD system - implemented a collection of simple and intuitive forkable template repositories to maximize team member productivity and reusability without sacrificing any customizability. Technologies leveraged were - Github, GCP CloudBuild and GKE, Google’s Kubernetes offering.

Large Scale distributed GCP to AWS data transfer appliance - designed and implemented a distributed multi part uploads system executed with boto3, pubsub and cloud functions. Allowed for customer required single file archives (up to 5TB) to chunked archives to be created and transferred in minutes not hours.

Privacy – Lead engineer for GDPR/CCPA Engineering wide compliance.

Infrastructure and Security – CI/CD owner and maintainer – Automation of global infrastructure built around Gitlab/Github/Kubernetes/Jenkins/IAM/Secrets Manager.

Data In/Out – 3-4 Billion plus events ingested daily near time ingestion and enrichment (golang+java+dynamo). Extensible event decorator framework. Numerous golang repos.

Analytics - Creator of BQM2 – Powers most ShareThis domo cards and first phases of our Adtech audience offering.

Data Science – Designed key pieces of data science pipelines. Limited but enthusiastic use of Scala/Spark/EMR.

Cost Engineering – Developed a drop in replacement storage scheme for ShareThis core data asset. Cost savings ~50% or storage and transfer costs.

Rallied team members through frequent all hands on deck cost saving and security related swarm activities.

Tracking Yahoo! user viewing history for all users of www.yahoo.com, news.yahoo.com, and other Yahoo sites. Component is responsible for a 10% lift in click through rate. Leveraging Avro, Hbase, Hadoop and Pig in the process.

Developed a Java modeling api to represent, maintain, and store the various outputs of Core's user and item grid based modeling engine. Provided framework for projecting model data to other optimized formats for use in content ranking.

Built a user profile and history publishing system for Core's geographically distributed ranking systems.

Built a grid based system of rate limiting for throttling hbase and external storage systems accesses.

Responsible for content ingestion for Yahoo's Core Team. Provided content de-duplication and normalization for Core's modeling and recommendation engines. Used ZooKeeper, HBase, Java, and Perl to develop both distributed and file based systems.

Worked extensively with Yahoo! customer facing teams to integrate Core's modeling capabilities into their internet real estate i.e. www, finance, news, answers, messenger, omg, and others.
