Sourwine serves as a Contract Specialist II within the FA4608 2 Cons Lgc unit of the Department of the Air Force, where he plays a pivotal role in executing mission-critical procurement actions to sustain Air Force infrastructure resilience. His responsibilities encompass the full lifecycle of acquisitions for facility maintenance, security systems, and communications support services essential to operational readiness across installations. Sourwine specializes in complex, performance-based contracts for air transportation support activities, ensuring compliance with federal acquisition regulations while aligning procurements with strategic readiness objectives. He routinely manages task orders under indefinite-delivery, indefinite-quantity (IDIQ) vehicles and coordinates with technical stakeholders to define requirements that meet stringent Air Force standards. Sourwine maintains consistent working relationships with a core group of contractors, including UNITED POOL MAINTENANCE LLC, WHITEDS ENVIRONMENTAL, INC., CALEB CRUCIAN, HALLIDAY TECHNOLOGIES INC, and ARABIC INTERPRETERS LLC. These partnerships reflect a focus on niche service providers delivering specialized maintenance, environmental compliance, technical support, and language services tailored to installation operations. His contracting approach emphasizes performance outcomes, clear statement of work development, and ongoing vendor collaboration to ensure service continuity in high-stakes operational environments. A defining feature of Sourwine’s portfolio is his exclusive use of Total Small Business Set-Aside authority under FAR 19.5, demonstrating a steadfast commitment to socioeconomic contracting goals. All of his acquisitions are reserved for small businesses, fostering equitable access to federal opportunities and strengthening the small business ecosystem within defense infrastructure support. He actively prioritizes firms with diverse certifications, including Service-Disabled Veteran-Owned, Women-Owned, and HUBZone entities, reinforcing the agency’s mission to promote broad-based small business participation. His procurement focus is narrowly concentrated on NAICS 488190—Other Support Activities for Air Transportation—encompassing services such as airfield maintenance, hangar operations support, security system integration, and logistics coordination critical to flight line readiness. This specialization underscores his technical expertise in the unique demands of military aviation infrastructure and his ability to translate operational needs into precise, compliant acquisition strategies.
