Kris Coleman
Engineering leader. Team builder. Platform architect. Human-centered technologist.
Experience
Over the past 15+ years, I’ve worn many hats: full-stack developer, consultant, architect, tech lead, and engineering director. But the throughline has always been the same—build great software, nurture great people, and leave systems better than I found them.
Currently, I serve as Director of Platform Engineering at TestifySec, where I help organizations secure their software supply chains with trust-first architecture. My work blends cloud-native infrastructure, continuous delivery, and a fierce commitment to team culture and mentorship.
I’ve collaborated with government agencies like DHS, enterprise security teams like Lockheed Martin, and open source communities like CNCF. My roots are autodidactic. My methods are people-driven. My results are impact-oriented.
