Dan Mullineux

I am a technologist with a focus on engineering culture and distributed scalable systems.

I have a strong record of safely delivering commercial value rapidly, technical leadership, process improvement, strategy and architecture. From startups to established corporate and government organisations.

I have over twenty years in all aspects of technology and leadership and still write code. I am inspired by the value that technology creates.

I focus on respect, motivation, support and solidarity, flexible remote and home working, optimising distributed teams with productive off-sites, training and conferences.

I enjoy the collaboration in tech, and the power of the community. I have created customer communities, self support, open source projects and open API's.

I have many recent years of decentralised distributed systems experience, but never underestimate the tradeoffs these and new technologies bring with them.

I constantly improve my craft, but know how to optimise to deliver value at velocity. Managing non-technical as well as technical risk, with automation and repeatability, continuous delivery, intelligent testing strategies, and quality feedback, from exploration, metrics, monitoring, tracing and alerts to manual user feedback.
