Peter is our Senior IT Engineer. After beginning his career in IT, he joined AHT in 2018 as an electrical apprentice, seeking a break from office life. It didn’t take long before he got back involved in IT systems, and since 2024 he has been almost entirely off the tools—though he’s trying to prolong it as long as possible! Peter brings a broad skill set across IT servers, networking, electrical systems, and communications, and is deeply passionate about his work. His current focus is on Operational Technology (OT) networks for large buildings—an often overlooked but critical area. Outside of work, he is a father of two boys and enjoys spending his spare time cycling.
