Sang Han

Sang Han serves as a procurement professional within the Contract Administration Services Division of the Department of Homeland Security’s Office of Procurement Operations, where they play a pivotal role in managing the acquisition of critical professional, scientific, and technical services that support national security and operational readiness. Their responsibilities include overseeing the full lifecycle of contracts for research and development, cybersecurity, and systems engineering initiatives, ensuring alignment with federal acquisition regulations and mission-critical requirements. Han routinely handles complex service-based procurements requiring high technical specificity, particularly in domains involving physical sciences, engineering analysis, and administrative support for large-scale federal programs. While specific contractor relationships are not publicly enumerated, Han’s procurement activity reflects consistent engagement with firms specializing in scientific research, testing laboratory services, and management consulting. These vendor partnerships are typically formed through competitive sealed bidding and request for proposal processes, emphasizing technical capability, past performance, and compliance with federal standards. The working relationship pattern is characterized by a focus on long-term, performance-based contracts that prioritize systems integrity and mission continuity over transactional engagements. Han’s contracting portfolio exhibits a strong preference for full and open competition, with 100% of awards issued under non-set-aside authorities. There is no indication of targeted use of 8(a), HUBZone, or SDVOSB set-asides, suggesting a procurement strategy centered on technical merit and capability rather than socioeconomic preferences. The primary NAICS focus areas include 511210 (Software Publishers), 541380 (Testing Laboratories and Services), and 541611 (Administrative Management and General Management Consulting Services). This reflects deep expertise in procuring software development, analytical testing, and strategic operational consulting services essential to sustaining DHS’s technological infrastructure and mission-critical systems.
