United States - Seattle, Washington

I'm Founder and CEO of Pulumi, a venture-backed Seattle startup.

Pulumi's infrastructure as code platform enables teams go from code to cloud faster with confidence. Pulumi leverages the industry's best languages and tools to help developers and infrastructure teams work better together, delivering unparalleled productivity and business impact. Pulumi is open source, with an easy-to-use SaaS for teams. Pulumi is used by thousands of the most innovative organizations.

Before Pulumi, I was Director of Technical Strategy and Engineering at Microsoft, responsible for developer and cloud tools, programming languages, and advanced technologies. I created the Compiler and Language Group to bring together all language, IDE, compiler, and static analysis products, across many languages (C++, C#, Visual Basic, F#), platforms (Windows, Linux, macOS, iOS, Android), and architectures (x86, x64, ARM32, ARM64). In addition to building and managing a world-class team, I was hands-on with product strategy, architecture, quality, and engineering.

In this role, I led efforts to drive more open source across Microsoft, including stewarding policies and initiating the effort and building the team to open source .NET and take it cross-platform.

I was previously Architect and Development Manager for a research operating system, Midori, and created its developer platform and its programming language. I launched, built, and led a team that delivered .NET concurrency, parallel, and asynchronous programming models, advanced safe systems programming in Windows, and rearchitected key aspects Microsoft's internal engineering systems, including source control, package management, and better internal collaboration.

I've been a software professional for over 20 years and have over 90 patents. I've written 2 books and enjoy speaking at conferences. My interests include developer tools, of course, but I love all technologies, particularly cloud and distributed computing. Nothing brings me more joy than building amazing teams to create innovative technologies together that solve impactful customer problems.
