Supporting continuous improvement of the Netflix app across multiple platforms by serving up data and insights about in-app quality of experience.

Lead a global team of engineers in delivering new identity graph features. Consistently deliver features (such as composite identifiers or multi-point queries) from inception to production each quarter. Work with stakeholders from multiple teams and departments to ensure all customer and business needs are met.Be a technical leader, advocating for good practices in code and in person. Drive a continuous cycle of improvement by gathering feedback and converting it to actionable initiatives.Maintain three-9's reliability of multiple critical distributed systems - a load-balanced Dropwizard API, a terabyte-scale Hbase cluster in HA mode, a multi-node Apache Flink cluster modifying the identity graph in real-time, a web of libraries dependencies spanning multiple teams, and more. Use logs, metrics, and intelligently-configured alerts to minimize disruptions to production capabilities (and engineers' sleep cycles).

Build a repeatable, scalable batch processing pipeline for customers' CRM datasets. Unlock the ability of sales associates to pursue opportunities for bulk data partnerships worth an order of magnitude more than previous API-focused customer deals.Refactor an aging Apache Crunch-based identity graph system to use modern Apache Spark, running on AWS EMR cloud infrastructure. Automation and performance gains reduced the need for engineer attention on a graph build, resulting in thousands of dollars and dozens of engineer-hours in savings per month.

Build and maintain an identity graph comprised of over 1 billion entities, 10 billion data points, and 10 TB of raw data. Design, analyze, and deploy technology and algorithms to deliver value to FullContact's core functions of identity resolution and enrichment by serving over 1000 identity queries per second, in pursuit of helping our customers Be Awesome With People.Evaluate and deploy technologies like Apache Kafka, Apache Spark, Dropwizard, and more on an AWS-based cloud infrastructure. Core products and functionality depend on up-to-date data being available across multiple backend and frontend systems and across multiple teams. Decide the right technology for a given task by evaluating multiple dimensions such as efficiency, development ease, and security.Work in a small team with agile methodologies. Interact with other software development teams in-house on a day-to-day basis. Interact with other development teams in a truly global organization multiple times per quarter. Work with product, sales, and marketing teams as necessary to translate customer needs into real solutions, and communicate to the company at large about potential opportunities to drive additional growth and value.

Design and maintain identity resolution and enrichment APIs which serve millions of requests per day. The services backing the APIs are written with modern Java and utilize AWS cloud services to be independently scalable and fault-tolerant under variable load.Head the design and implementation of a system to deduplicate images/photos in contact records with high accuracy (90+% P/R) and minimal delay (<10ms). The system is responsible for improving the quality of images in hundreds of millions of images in customers' contact records.

Worked on a team of 3 to develop a functional test suite for a production Grails API, and the accompanying DropWizard refactor, as part of an effort to move to a more maintainable codebase.

Worked on a team of 3 to:- Develop an algorithm and accompanying library for identifying visually similar images.- Improve the security and functionality of an internal Grails web service.

Worked with a team of 4 to design and implement an in-office, networked software solution to connect a pair of arcade machines and an accompanying website for high score extraction and tracking.Worked in a group of two to identify problems with, and improve functionality of, h.264 encoding in a Flash media wrapper.
