Shayn Tierney

Shayn Tierney serves as a key procurement lead within the U.S. Agency for International Development’s Mission Operations and Administrative Affairs (MOAA), supporting the agency’s global development mission through strategic acquisition of professional and technical services. Responsible for managing complex contracting actions, Tierney facilitates the procurement of high-impact advisory services critical to institutional strengthening, governance reform, and emergency response coordination in partner nations. Their portfolio primarily encompasses consulting services that enhance public sector capacity, policy design, and democratic governance frameworks, aligning closely with USAID’s core objective of sustainable development through local institutional resilience. Tierney maintains a consistent working relationship with AMD INTERNATIONAL TECHNOLOGIES LLC, a primary contractor delivering specialized management and technical advisory services. The procurement pattern reflects a preference for established firms with demonstrated expertise in international development contexts, with engagements typically centered on long-term, performance-based task orders rather than short-term tactical purchases. These partnerships emphasize deliverables tied to capacity building, stakeholder engagement, and systems improvement across fragile and transitioning economies. There is no set-aside preference in Tierney’s contracting activity; all awards are competed fully and openly under the general services umbrella. This reflects a mission-driven focus on technical merit and implementation capacity over socioeconomic classifications, indicating a procurement strategy prioritizing outcome efficacy and institutional alignment over targeted socioeconomic set-asides. The primary NAICS categories under Tierney’s purview—541611, 541690, and 541990—reveal a deep specialization in administrative management consulting, technical advisory services, and broader professional support functions. Procurements center on governance diagnostics, institutional assessments, policy analysis, and program evaluation services, underscoring expertise in complex, context-sensitive development environments requiring adaptive, evidence-based solutions.
