Summary

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

I lead the FaaS/Serverless platform at Netflix, which powers the next-generation Netflix API. This platform processes and orchestrates all requests from Netflix clients to backend systems — leveraging new technology such as Docker, Node.js, gRPC and Amazon ECS. This effort is a significant cross-functional project which involves orchestration between many teams and stakeholders across Netflix.

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

Previously, I was part of the platform team at Amazon Web Services — where we launched services such as AWS IAM and worked on the metering and aggregation 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 am also the lead maintainer of the open source REST framework Restify.
