Mr. Iannacone has more than 25 years of mission-critical engineering and construction experience, including oversight of more than three gigawatts (GW) of completed data center capacity across both individual facilities and large-scale campuses. He previously served as Director of Project Management at Amazon.com, Inc., where he led the development, construction, and deployment of Amazon's AWS data center and ATS Sortation and Robotics facilities across North America. In that role, he managed teams of more than 100 personnel and oversaw the distribution of more than $500 million in capital for new development site builds and other projects. "Converting existing utility-backed mining infrastructure into purpose-built AI data center capacity requires disciplined execution, technical depth, and proven leadership in mission-critical environments," said Jerry Tang, Chief Executive Officer of BlockchAIn. "Chris brings that combination. His experience overseeing large-scale data center development, including more than three gigawatts of completed data center capacity, leadership of AWS data center infrastructure across North America, makes him an important addition as we advance through our next phase”. An engineer with expertise in electrical and mechanical systems, Mr. Iannacone holds a degree in Applied Sciences/Engineering from the City University of New York. Earlier in his career, he delivered mission-critical infrastructure projects for major institutions, including ABC, NBC, and the New York Stock Exchange. "BlockchAIn's strategy, converting existing utility-backed mining infrastructure into purpose-built AI data center capacity, addresses one of the most important constraints in this market, which is access to power on a defensible timeline," said Iannacone. "The Company has several sites that can become purpose-built AI data center capacity, and I look forward to leading the execution required to move these projects through conversion and commissioning." About BlockchAIn BlockchAIn is a developer and operator of digital infrastructure focused on AI hosting and high-performance computing workloads. The Company's platform combines access to reliable, scalable power resources with modular infrastructure deployment designed to accelerate the development of next-generation compute capacity.
