Summary

I’m an engineering leader with a passion for cloud computing (IaaS, PaaS), distributed systems, big data, and security. I have experience leading and delivering successful cross-functional teams and projects.

I am a seasoned public speaker — having given talks at many industry-leading conferences such as O’Reilly Fluent, QCon, Node.js Interactive, and Container Camp.

I’m currently leading the creation of the next-generation Netflix API, which processes and orchestrates all requests from devices to backend systems. This effort is a significant cross-functional project which involves orchestration between many teams and stakeholders.

I’ve contributed to the industry leader in cloud computing at Amazon Web Services. I was part of the team that launched AWS IAM and created a horizontally scalable metering platform used by all AWS services. At Joyent, I was part of the core team that built a public cloud (SmartDataCenter) and object store (Manta) from scratch.

I have a proven track record of owning and leading cross-functional technical projects including design, implementation, testing, operations, and deployment.

My professional experience has been in the infrastructure as a service (IaaS) space with a focus on scaling out distributed systems from hundreds of request per second(RPS) and megabytes of data to millions of RPS and terabytes of data.

I am also the lead maintainer of the open source REST framework Restify.

Experience

Principal Engineer/Architect at Netflix.com

Launched the Joyent Manta object store and compute service. Manta services I architected, designed, and implemented:

Highly available automated database fail-over system built using Node.js, PostgreSQL, Zookeeper, and ZFS. (github.com/joyent/manatee)
Horizontally scalable authentication service built using Node.js, redis, and LDAP.
Manta metadata partitioning service utilizing Node.js over a custom TCP protocol, built on top of a custom consistent hashing library and LevelDB.
LDAP replication service built with Node.js and LDAP.js

Consulted with the Joyent-sponsored Node.js project lead on features of Node.js.

Senior Software Engineer at Amazon Web Services
