Matt "Kelly" Williams

Waste is a bug.

Matt “Kelly” Williams is the founder of Making Software Greener and CEO of the Sustainable IT Manifesto Foundation. He helps engineers see how architecture, DevOps, and AI shape performance, cost, and sustainability—and why they’re really the same problem.

With over three decades in IT, Kelly has worked across DevOps, cloud computing, and software architecture. He serves on the advisory board of the Green Computing Foundation and speaks internationally about sustainable software, developer agency, and the hidden inefficiencies that shape modern systems.

He has always wanted to be a Renaissance person; perhaps one day he will be. In the meantime, he explores sustainable computing, photography, tabletop game design, weaving, cooking, and wandering the mountains near Loveland, Colorado.

Systems remember every decision we make.
