About Sotiri Aggelis

With 18+ years of experience spanning EMS/BAS systems, data integration, and vendor management, I\'ve built my career at the intersection of operational technology and enterprise strategy — starting as a hands-on systems technician and growing into a Director-level leader driving national vendor programs in the HVACR and facilities space.At Verantum, I lead end to end vendor lifecycle management, from sourcing and onboarding through compliance, performance oversight, and continuous improvement, ensuring our vendor network consistently delivers against customer SOWs and SLAs. I\'ve built the KPI frameworks, dashboards, and reporting structures that bring accountability and scalability to complex service programs.My technical foundation in BAS/EMS and data integration gives me a unique edge: I understand what\'s happening on the ground, and I can translate that into data-driven decisions that matter at the leadership level.I\'m passionate about building operational systems that scale — ones where the right vendors, the right data, and the right processes come together to deliver results.
