Profile: https://flows.cv/marklillibridge

I love understanding, designing, and building distributed systems.  I particularly love diving deep into the details of a system to solve hard problems, be they protocol correctness bugs, consequences of emergent properties, or performance issues.  I am also passionate about learning, mentoring, and setting a high quality bar for code reviews and on-call.
