About John Hoffman

Human first, engineer second; driven by a genuine love for people. With little tolerance for "busy work", I'm most excited by clear opportunities to change people's lives for the better. Show me how I can help you do that, and I'll happily join your cause!I'm proud of my ability to tackle diverse software engineering problems with an eye to business needs and bottom lines. My most recent professional work is in the world of FaaS with backend services written in Scala/Akka, and I'm currently wrapping up a 18-month self-funded sabbatical exploring some entrepreneurial and technical interests (DDD, ES, CQRS, CRDTs, offline-first apps, utility/serverless computing, using NodeJS and ReactJS).
