Principal Software Engineering Manager at Microsoft. He leads a team in CSE, “Microsoft’s superhero team,” helping the company’s biggest customers drive effective change on the cutting edge of technology. He’s been an Open Source developer and advocate for 20 years, mostly while consulting for some of the world’s largest NGOs. He also practices ninjutsu, sings with the opera band THE CAST, and parents three (dangerously adorable) children. Campbell is generally opposed to computers on principle and encourages everyone to return to traditional methods of computation like fingers or perhaps an abacus. He is working on the first Kubernetes cluster running entirely on children’s counting blocks.
