Khalil R. Mack

Khalil R. Mack serves as a Contract Specialist within Washington Headquarters Services, supporting the Department of Defense’s mission to modernize institutional management systems and enhance enterprise-wide operational efficiency. In this role, he manages the full lifecycle of professional services acquisitions, with a primary focus on research and development, computing infrastructure, and administrative consulting contracts. His work ensures alignment with federal procurement regulations and DoD strategic priorities, particularly in digital transformation and resource optimization. Mack specializes in complex, performance-based solicitations that require technical rigor and compliance with FAR and DFARS requirements, frequently engaging in competitive negotiations and source selection processes for high-impact, mission-critical services. Mack maintains established relationships with a core group of contractors including CLARITY INNOVATIONS LLC, CYNERGY PROFESSIONAL SYSTEMS LLC, SIGNATURE RENOVATIONS LLC, AMD INTERNATIONAL TECHNOLOGIES LLC, and GUIDEHOUSE INC. These partnerships reflect a consistent pattern of engaging firms with proven expertise in technical research, data systems, and management consulting. His procurement approach emphasizes vendor reliability, past performance, and technical capability, often resulting in repeat engagements with contractors who demonstrate agility and compliance in delivering complex, high-stakes services to DoD components. While the majority of his acquisitions are conducted as full and open competitions, Mack consistently allocates approximately 35.6% of his portfolio to Total Small Business Set-Asides under FAR 19.5, reflecting a strong commitment to small business participation. He does not routinely utilize specialized set-asides such as 8(a), HUBZone, or SDVOSB, but his emphasis on small business eligibility ensures broad access for qualified firms without socioeconomic designations. His procurement focus is concentrated in NAICS 541712 and 541715, underscoring a deep specialization in physical and engineering research and development services. He also frequently procures computing infrastructure and data processing solutions under NAICS 518210, alongside administrative management consulting under 541611. This technical profile highlights his expertise in supporting DoD’s digital modernization initiatives through science and technology-driven services.
