About Joe Duffy

I\'m Founder and CEO of Pulumi, a Seattle startup reimagining cloud computing.Pulumi helps developers and infrastructure teams build better software together. Pulumi\'s flagship infrastructure as code engine is open source and stands on the shoulders of giants with great languages and tools, yielding best in class productivity and faster time to market. Pulumi\'s infrastructure management platform also now features new security and compliance products and is increasingly using agentic AI to reshape the practice of infrastructure engineering. Pulumi has over customers, a community of over practitioners, and hundreds of employees worldwide.Before Pulumi, I led developer tools strategy at Microsoft and managed engineering groups spanning developer and cloud tools, programming languages, static analysis, and advanced technologies. I created the Compiler and Language Group to bring together all language and compiler tech across many languages (C++, C#, Visual Basic, F#), platforms (Windows, Linux, macOS, iOS, Android), and architectures (x86, x64, ARM32, ARM64) under one roof. I also led efforts to drive more open source across Microsoft, including building the team to open source.NET.I led the developer platform team for a distributed type, memory, and concurrency-safe operating system, Midori, creating its programming model and language. I launched, built, and led a team that delivered.NET concurrency, parallel, and asynchronous programming models, incubated task and data parallel libraries, and software transactional memory, and other core technologies that eventually led to async/await in popular languages like C#, C++, JavaScript, Rust, and Python; 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 nearly 30 years with over 100 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.
