Her technical domain expertise lies in earthmoving and ground preparation for military construction, requiring deep familiarity with DoD engineering standards, environmental mitigation protocols, and installation-specific constraints. She ensures all awarded contracts meet stringent military specifications for durability, safety, and mission continuity.
