Founder/Builder (YC W26, ex Meta, ex X)

I am CEO of Crosslayer Labs where I oversee the development of the leading solution to defend against Internet infrastructure attacks. Previously I was research software engineer at Princeton University in the CS and ELE departments. I primarily worked under professors Prateek Mittal and (now Princeton University provost) Jennifer Rexford on Internet security and privacy. I specialize in understanding and defending against cross-layer network attacks and have done extensive research on the Border Gateway Protocol (BGP). I am an inventor of Multi-Perspective Issuance Corroboration (MPIC) which helps protect HTTPS connections from BGP attacks. MPIC helps secure the issuance of all ~8 million HTTPS certificates signed every day as it is mandated by the CA/Browser Forum through an industry standard I wrote. I am also a founder of the Open Multi-Perspective Issuance Corroboration Project (Open MPIC) which provides open-source implementations of MPIC which are used in production by several leading CAs.

Working at the intersection of defence, robotics, and autonomous systems, I create hardware that performs reliably in the world’s most demanding environments. My work is grounded in direct collaboration with end users — military operators, EOD technicians, and field specialists — ensuring every design decision is shaped by real operational needs. As Founder of Seeing Systems, I lead the design of autonomous aircraft capable of independent operation and resistance to electronic warfare. At Wildcat I.S., I designed EOD training and diagnostic systems now used by armed forces across Europe — merging advanced electronics with ergonomic, human-centred design. My goal is to bridge the gap between cutting-edge technology and real-world usability.

Founder and Software Engineer. Achieved a first in Physics at Cambridge, then switched to Computer Science at Master's Level, and somehow came top of the year. Lived in Guernsey, Hong Kong, London, San Francisco.

Building Mendral, an always-on AI DevOps Engineer that observes, diagnoses, and fixes CI and delivery reliability issues. Think self-healing pipelines. Previously co-founded Dagger (YC W19), making complex software workflows repeatable and reliable. Before that, I was the first hire and eventually VP Engineering at Docker (formerly dotCloud). From 2010 onward, I scaled the team from 3 to 100+, and built and led teams behind Docker CE, EE, Docker Desktop, Compose, and the open-source core that helped reshape modern infrastructure. Angel investor and advisor to early-stage startups since 2018. I care about infrastructure, automation, developer productivity, and building cultures that turn ambition into sustained engineering velocity.

Building Mendral, an AI DevOps Engineer that fixes CI before you notice it's broken. I wrote Docker's first lines of code. Back in 2011 at dotCloud, I helped create what eventually became known as Docker. Then I set up Docker's first CI in 2014 and watched it break in all the ways CI still breaks today. After 7 years at Docker, I co-founded Dagger with Sam Alba and Solomon Hykes to make pipelines portable. Now we're back at YC (W26) building Mendral. After 15 years, I still think CI is a problem worth solving. Ex-Google (Storage Infrastructure) · Ex-Microsoft · 2× YC founder
